SD-1 and TS-5 mods

I received my SD-1 and TS-5 in the mail today from STRATDELUXER97; aka Pedal_Tweaker, aka John, (I hope he doesn't change his screename again any time soon....lol); who did some very cool mods to them. I just got through trying 'em out with my Strat and Les Paul. I compared the SD-1 to my modded DS-1 (also John's work) using them with my Les Paul and found the SD-1 to be warmer in tone than the DS-1, very vintage sounding as if playing through a Marshall amp. Excellent for a Foghat-type sound. Not too much distortion, which is what I wanted, I can crank the dist. all the way where it sounds almost a little fuzzy and still not be too overboard, but the gain is fine. The DS-1 has more crunch to it and more high-end and headroom, but the SD-1 definitely has earned a place in my effects chain as a good rockin' effect for rhythm power-chording and can be used for lead also. What's nice about the two pedals is the fact that I don't have to crank my amp up to get "that breaking up" sound I would get if I cranked my amp alone instead . Too hard on my ears with that DRRI amp and it's notorious brightness. I haven't tried my Strat through the SD-1 yet, but I'll post a review in this thread a little later.
The TS-5 totally and very pleasantly suprised my ears when I first used it with my Strat. I A/B'd it with my modded TS-9 and found the TS-5 to be crunchier and with a little more headroom than my TS-9 which has also had the dist. part of the effect modded, too. Adding my Voodoo Labs MicroVibe and a little echo to the mix with the TS-5 and I could've swore Robin Trower was standing next to me playing Bridge of Sighs. Great sustain. Way cool! SRV-sounding licks are a cinch with that high-end crunchiness combined with that nice tube-sounding smooth boost. I noticed just a very small amount of noise while in use during a pause in a riff, but I expected that from this type of pedal and it's very minimal. Unoticeable while playing.
My Les Paul really screamed through the TS-5 when I played some lead riffs, holding it's sustain for as long as I needed it, and when boosted up enough the sustain would turn into a really cool feedback.
This TS-5 has also earned a spot in the lineup and is a keeper. I had one a few years back and didn't keep it for long 'cause I thought it sounded kinda cheap, and looking the same. But there's no cheapness to the sound of this TS-5 this time around, and even though it's housed in a plastic case I'm pretty confident it'll stand up well as long as it isn't abused too much.
I wish I had recording capabilities right now so I could let you all hear what they sound like, but suffice to say that being a huge rock/rock n roll fan for 40 years and a guitar player for over 30 of those, I give both pedals two thumbs up. Of course all of the above is my opinion only, and I wouldn't mind hearing from others who have the same pedals modded to John's specs.
I strongly recommend John's mods if anyone is interested in either doing them on their own, or contacting John and arranging to have him do them. You can find more details about his mods at his thread in the Vault Room.
For only spending $35 for the SD-1 and $25 for the TS-5 on eSchmay and putting just a few more bucks into them by having John mod them, I feel I have made a few very wise investments.

My $.05 worth

ROCK ON, PEOPLE!!!

Wow....you,ve made me happy Bob that you like the pedals...That's great...I told you you'd like what you heard...;) You've made my day buddy...Make some inspiring music buddy..

John
 
How different are your mods compared to Robert Keeley's? Same concepts or going for something different?

Thanks!

Mike
 
good review, mm ...

as you know, I agree, John does a great job on his mods ...

I noted that in my review of the SD-1 & DS-1 on the "old" forum. For those who are interested, here's the link:

As far as specifics, STRATDELUXER97 is more qualified to comment that than I am. I think John's mods are in the same arena as Keeley's but I believe John uses some different components for certain values.
Maybe John will chime in and give more detail.
-Bob
 
from what I understand from my emails with John, the DS-1 at least is very similar ... but I also will let John address that

Well...I don't know since I don't own any Keeley pedals? I do know that I was modding Tube Screamers(TS5s) on e bay several years ago while Keeley was still in the military! :D
For me it's just a fun hobby and I voice my pedal mods with the same ears I've used to mod amps and everything else I can tweak in someway or fashion...It's just for fun really and it's not a business...I have a great job really..You'd have to tell me more about Keeley's mods I guess? ;)

John
 
Heya John...I have a TS5 & a TS7...and I really love the 'hot' switch on the TS7, as well as the original tone..is it possible ti *add* a TS7 'hot' style switch to the TS5?

Basically the mods come down to tweaking cap and resistor values by having the schematic in front of you...I can't say that my mods are identical to Keeley's but I will say that we have spoke to each other...I'd imagine some of my cap values would have to be different and the way I voice the distortion sections of my pedals is going to be different...He uses an LED to generate more distortion in his DS1 "Seeing Eye Mod" The SEM is actually the LED flashing....I sometimes like to stick with the stock silicon diodes or mix and match silicon with germanium or 4002s or even the 1N34 diode for asymetrical clipping...There are tons of ways to re-voice a pedal and it isn't rocket science but you also have to try things,different values,and trust your ears....With the Tube Screamers,I always found that when you'd step on a stock unit,you'd lose your low end..I used to beef up the input stage and tweak to higher value caps to get more lows....From there,I then wanted more gain so I'd tweak the gain stage resistors and caps for more gain and more balls...Some of the Boss pedals are similar to the TS series,especially the SD1...An SD1 can be made to sound identical(almost)to a Tube Screamer with some tone control,clipping stage changes,and changing over to the output stage resistances of an 808....It's alot of fun but it's tedious work and if you screw the board up,the pedal is pretty screwed up also unless you start hard wiring things and that looks tacky and very unprofessional in my book...So...That's my short story....Am I directly copying the Keeley mods? No I'm not....Do we both have similar tastes and or ideas?Probably.....Keeley charges pretty big bucks for the mods but I also know his stuff is great from what I read....Again,just a fun hobby for me and I'm not getting rich over it....

John:D :D

The circuit board fastens right up to the back of the TS5's plastic case....That switch just puts another cap in parallel with the stock cap and gives you more lows and more balls....I know at one point I tryed adding a switch to my own TS5 early on when I started on the TS5s and had no luck because things were kinda tight....I like to mod the pedals so they look stock and only change the size and led colors,otherwise I Like to get the pedal to sound good enough so I don't have to rely on too many other gadgets etc....It's just easier on me,plus the more time it takes to do the mods,the more the mods cost...I say K.I.S.S. :D

I need to add in here all that I'm not trying to sell mods via the forums....If you want to know about how to mod your own pedal etc...Ask away....

Here's 1 of many feedbacks that I found on page 1 of my E Bay feedbacks regarding 1 of several Tube Screamers I Modded....Notice the date....This is from my actual feedbacks under "johnnpr" My e bay screen name....;)

Great communication, delivery & product! Thanks for the great Blues Pedal John! davohh( 20) May-29-00 19:31 331726288
Reply by johnnpr: Dave,Great guy! Glad you dig the pedal.Fast,reliable,prompt payment! #1buyer!
 
Ahh gotcha...1 more question....if I were just to do the mod, not the switch, does the gain and tone have enough range to cover the non-modded TS5's levels? I don't mind changing knob positions if I have to, but sometimes I like the milder gain and tone of my TS5.

Just roll your guitar's volume control back but it's going to depend on where your pedal's drive level is set...Also I revoice the pedal for more fullness in tone,so it's not going to sound just like a stock TS5....I leave the Tube Screamer mids in place but add more gain,more balls,and use much better components and the correct sounding opamp in the mods...We live real close to each other and you're welcome to listen to my pedals if you like...I'd bring whatever you'd like to hear to the store for you...

I haven't had a chance to put my modded SD-1 through all of the paces yet due to the wife being ill for so long and work being unusually busy. However, I did have a chance last week to get about 15 minutes with the pedal at lower volumes.

It is significantly smoother versus the un-modded. It also seems a tad bit darker, although the low volume may have had some effect on that. If it is darker, one of my objectives will have been achieved. The pedal always sounded somewhat metallic, but anytime the tone was set above 12:00 the highs were just unbearable to me. I'm hoping the gain will be slightly greater, although if the transparency is improved (which I believe it is) the gain will sound better, thus achieving the same goal. I have about 5 minutes worth of short clips recorded before the mod using various settings and degree's of level and gain. I detailed the exact amp and pedal settings in writing, and hope to have the time soon to do the after version using the same settings and guitar.

I already have no doubt that the pedal sounds much better than stock, just due to my short time playing with it. I don't use the SD-1 as an actual overdrive pedal. I use the gain channel of my Marshall for that. The SD-1 is for now used as more of a boost pedal, so I wanted something that was smoother and had a little more of a singing quality. I think this will deliver.

Once I get my Marshall modded to have a much more useable clean channel, I would like the option of using the SD-1 as a mild to moderate OD pedal, in effect giving me 3 channels.

John does great, quick and professional work.

Wow guys...Thanks for posting your tonal thoughts back to me on the pedals...Jeff...The SD1 is very close overall to the Tube Screamer circuit with just a few minor differences...The SD1's tone circuit has some different eq values,has 3 4148 silicon diodes for it's clipping circuit vs 2 in the Tube Screamers...Both use the 4558 chip but the SD1s chip isn't the JRC4558D so I change those out...Tonally the SD1 has more aggression and isn't quite as warm as the modded Tube Screamers..The SD1 has more gain overall and I tweak cap values so the pedal isn't so darn bright with the tone control back low...The DS1 suffers the same problems..I Like the sound of the SD1 after mixing and matching clipping diodes with a combination of the stock silicon and the 4002 or an 1N34 diode as it changes the distortion character..The combination of bigger caps and better quality caps and the removal of tone sucking metal can caps,allows us to get some better tone from the pedals...The pedal is also quieter because I also use metal film resistors and real good quality caps...It helps but it's mostly the changes in values that makes the pedals sound the way they do...That's the trick.Knowing where to make the changes? ;)

John, is there a way to take a little more of the metallic sound out of the DS-1, and if so, is it something I could do fairly easily with the proper component(s)?

Bob...Where are you setting the tone control and where is your drive levels set at? Probably need to change a cap value...Are you wanting the tone a bit looser or just some more highend removal?

Bob...I'm now using a JRC inline opamp for the DS1s that seems to be smoother...You might try changing D5 from it's stock silicon 4148 diode over to either a 4002 or a 1n34 diode...You're probably liking this tone because your TS5 and SD1 has this setup and you percieve your tone as being smoother with the combination of 1 silicon diode and 1 other different diode...On the back of D5 and D6 there's a 47pf cap across the diodes....You can double this cap to 100 pf if you like...After these mods,some things you'll notice...The pedal will lose a bit of it's tight british Marshall type crunch and it'll sound more compressed...

I would first just try to substitute D5 to a 4002 and that should do it,providing you also like the overall eq of your DS1? The components are marked on the board...Make sure you get the diode band soldered correctly and don't overheat the delicate board...Just cut the diode off the board first,carefully heat the soldered ends and use a toothpick to push the old leads out of both diode holes...Put the new diode in with the band facing the correct orientation as the one you removed,resolder the new diode in and you're good to go...Try this first before doing anything else cause I think this is what you're looking for,in fact I Know it is! ;) I also have some great board photos if you need to reference the components...E mail me buddy..

I don't want to lose the crunch, but I do want to trim the high-end a little, compress it some. It just sounds a bit metallic in comparison to all my other dist. pedals.
I set the controls with the tone at about 12:00 o'clock, with the level and dist. set at 9:00 o'clock. If I turn the tone down much more it starts to sound a little muddy. I don't want to end up with a dark sounding effect as the SD-1 covers that area nicely if desired.
Where can I get one of those 4002 diodes you wrote about? I tend to stay away from Radio Shack as a friend who's done mondo electronic projects advised me of the lesser quality components they sell. Mouser probably, right?
Just an additional comment:
I never thought I'd buy and use another Boss pedal because of the way they tend to suck the tone out of my rig, but the modded versions of the ones I recently acquired really rock the house!
That TS-5 is a real phenom.

Rock on.

I'll send you whatever you need buddy....No problem...The pedal needs to suit you and your tastes 100% before I'll be really happy....;)
