Boss SD1

allright, here it goes.

i'll say right off the bat, if you want to play heavy metal with this thing, forget it.

i can see why blues and rock players like it though.. at lower gain stages, it does overdrive the amp a bit, but at higher gain, it just adds noise and nothing else.

i moded it, with what parts i had at home, and the noise level is slightly lower, compared to stock, it is also percievably louder, but at a certain volume, it stops doing anything but adding noise, since you cant percieve that small increase of volume.
it tightens the amp up, a small bit though.

moded it from a couple of pointers from peeps i've been talking to, aswell as the things Erik, has written on its page.
gotta say, it's easy as eating pie and you can hear the results, but like said, unuseable for metal.
gonna change the C7 and D4 and see how it fares then.

plus:
less noise, more volume, slightly tighter responce

minus:
doesnt work at higher gain setting.

and again, good for blues and hard rock, but dissapoints at metal (though you can play iron maiden stuff on it.. aswell as judas priest.. and a lot of classic metal. lets just say 80's stuff it does well... but a bit more modern, turn somewhere else, cos it dissapoints.)
 
Re: Boss SD1

So, then, do you recommend the modded SD-1 for metal? :chairfall

The Super over drive isn't super enough, eh?

Re: Boss SD1

indeed... for a Super Overdrive, it's not superly overdriving anything lol


for maiden it's pretty good though
 
Re: Boss SD1

I've never been under the impression that metal guys used the OD for anything besides boosting their existing tone a bit. Are you trying to get the majority of your gain from it?
 
Re: Boss SD1

The metal guys I have seen using it are hitting the gain channel of there amps with it. Crank the volume and tune the tone and gain to taste basically.

I like mine into the front of a clean or slightly dirty amp.

no.. i get the majority of the gain from the amp. i use it as a volume boost.. the level is up high and the drive bit is pretty low.. below 9'o clock. if i turn it up high i get a hornets nest. if i turn the gain on the amp down, the distortion sucks
 
Re: Boss SD1

That behavior (level up + drive up = hornets nest) is man overdrive pedals out there. If you're running the level flat out, turn the drive down. If the drive is up, turn the level down.

These things are designed to "push" an amp to overdrive and add some clipping of their own. In to an already overdriven amp, the drive should be down. With a clean-ish amp, turn the drive up.

The "mush" that you hear is usually due to hitting the gain threshold of the amp, or exceeding it. Mess with amp/pedal settings to find the sweet spot.

And don't tell Mr. Wylde it can't be used for metal. He did for years and in to BLS stuff before going to MXR (which is a SD-1 clone in itself). ;) But I hear what you're saying and I will agree there, older classic metal it's fine for but for newer, gainier stuff, definitely look at something else.

What all did you change?

Oh, and ceramic caps *will* allow more noise in the circuit vs. good poly film or metal film caps. Even 1% resistors in certain spots will help.
 
Re: Boss SD1

i found the sweet spot kinda..

though it's pretty limiting, if it can be used only on and around that setting..


i got the gain on the amp at aroung 5. the EQ is 665 (bass, mids, trebble) i got the SD set with level on full and both tone and drive are pointing to the E (of the tonE)

it works pretty well. tightens up the amp on that setting considerably, aswell as adds some edge to it.
anything above that, unless the pedal is moded specificaly for highgain, is just asking for more noise.
 
Re: Boss SD1

There ya go. That's how to use it, one way anyway.

When the SD-1 and it's predecessors came out, they were used to push amps to higher gain levels with much much lower gain than what is available today. We're talking JMP, Plexi, JCM800 gain levels.

i know... and.. dont know at the same time lol



my amp is brutal in that respect. it's got quite a lot of gain on its own (and keep in mind, i'm hitting it with a pickup that has 22.5k resistance, with a big fat A5 magnet) and the sd1 doesnt help in that respect.

i think, it should be moded into a pure volume boost, with low noise and high clarity. then i think it would be more useful, when i crank the gain to 8 :D

and, if you havent noticed yet, you got a PM

Re: Boss SD1

My SD-1 is all stock, and it works perfectly for boosting an amp. It's just that the majority of the fuzziness has to come from the amp. Kirk Hammett used a TS9 Tube Screamer for a long time, and when I got my TS9DX, I didn't really understand it. And Zakk Wylde is a big fan of the SD-1. But depending on these pedals for high-gain tones becomes very unsatisfying. I actually like using a heavy distortion pedal set to a low gain/high volume setting mixed with a little natural tube fuzziness.
 
Re: Boss SD1

very tricky that SD-1. I used to have a marshall JCM800 combo that would go into hyper old-school kill 'em all distortion using an SD-1. but through other amps, nada. basically a tube screamer with the diodes in a different configuration.

considering the year it probably came out, it's not too surprising it doesn't do modern sounds, but I'm surprised it doesn't sound heavy with yer laney.

it cant keep up with it on higher gain settings, that's the problem.

mid gain + SD1 = coolness

high gain laney alone > high gain + SD1 .. it sucks the tone out of the amp =P
 
Re: Boss SD1

Thats why i bought a modded SD1 off of Mr. John Spina. Stop being foolish davey! :laugh2: Does all the 80s stuff and can sound modern without adding one bit of noise.

But why would you ever need that much gain? The amp alone is probably capable of reaching saturation on its own. There is no point in adding more. You just get what you described. You just want more volume at that point and the SD-1 is not the best choice for that. The SD pre pedal or a Fulltone fatboost are much better suited. I have an old Voodoo Lab overdrive that will do ridiculous volume boosts with virtually no distortion at all that I use for that purpose.

I like mine into the front of a clean or slightly dirty amp.

This would be the main use for it on most places. A boost I would guess.
