DR Z Prescription Jr Review

We are finally in the same state at the same time! The amp came in last Thursday afternoon and I left for CA at 6am that morning. My bro, Keith, got the pleasure of picking up the box and getting to play it for the first time for a few days. Out of the box Keith told me that it was very icepicky/ratty at first but after a couple of days that all went away. I'm assuming that was the carbon comps setting up. When I got home Tuesday night I sent my wife over to Keith's to get my pug and my Z....she's an awesome woman. I only got to play it for about 20 minutes that first night, but wow......chime for days and cleans that will make you cry. The next day I was able to open her up. First off the tone controls don't react like other amps, they are much more interactive that what I am used to and I'm slowly figuring it out. The master volume is one of the best I've heard, the Divided by 13 being the best. There is no tonal degradation that I can hear down to a whisper. One of the biggest things that I am getting used to is the soft sag of a 5y3. I did make an improvement right off the bat by swapping out the stock 5y3 with an old big bottle Sylvania that I had. It tightened the lowend up a bit. I think that I will try a 5ar4 just to see if it tightens it up even more. Not that I'm not happy with the 5y3. Speakerwise, I started out with the 2x12 with the G12H30/Greenback....sounded beautiful. I tend to take my 1x12 99% of the time anymore so that was the next experiment. I started out with an 8ohm G12H30 which has always been my all time favorite speaker. It sounded good, but the lowend was a bit unruly. Swapped out for the 16 ohm Greenback and it came clear why the good Dr voiced it for GB's. It's a great match even in an open back cab. I've still going to hear it with Keith's Celestion Blue and the Gold. The gain is not quite as much as what I was expecting, but I also haven't tried it with 'buckers yet. That said, it truly is a guitar+chord+amp=incredible tone type. It's by far the most articulate, touch sensitive amp I've ever played....which will show your shortcomings immediatly. It will make a better player out of you! Tonally it is very voxy, but warmer. They write up the description as a cross between an AC30 and Dumble. It takes pedals very well, but I'm not sure if my beloved OCD is the right one for it. The build quality is perfect and I'll have to take some gut shots later of the chassie. It's also a very quiet amp even when cranked and the Overdose engaged. I am happy!

I don't believe this review. Please send the Dr. Z to my house and I will see if I can concur with your findings.;)

Nice amp, enjoy it. You might want to try a little less bottom heavy OD than an OCD. I bet that Bad Monkey might get along a little better with it.

LOL! I did try the Bad Monkey and it sounded nice, but I am also starting to get a very light ticking sound when I engage the BM. I also noticed that some of the top end sparkle disappears when it's in the chain....so I took it out. I'm kicking myself for selling the Zendrive now! I'm going to put myself on the list with Alf soon to get a new one.
 
Re: DR Z Prescription Jr Review

A fantastic amp indeed! I had a Dr.Z Maz 38 for about 2 years. Didn't get a lot of play time but it was a nice one. Had effects loop & reverb. I agree the Divided by 13s are a very small step up but eh fantastic nonetheless. Did you get the effects loop? It's amazing how those amps can pickup everything from the pickups to the guitar wood & springs in your trem!
 
Re: DR Z Prescription Jr Review

Sweetness. Posts like this are why I continue to jones. Seriously, you've got great taste, and I dig all of it. I don't normally like pastel guitars, but that tele is killer.

I'd love to throw that Dr. Z and OCD on my pile especially.
 
Re: DR Z Prescription Jr Review

Sounds good Ryan! My new Z should be in tomorrow....so we'll both be singing the Dr.'s praises for a while! :D

Being yours has the 5Y3 you could take numerous small steps up in firming up the power supply. The Doc's amps will accept 5Y3s, 5V4, 5U4, or GZ34/5AR4. I tried my Rt.66 with the 5V4 and thought that it gave it a really cool singy quality when cranked which really excelled for lead tones.

BTW If memory serves the only amp that uses CCs is the EZG-50 I think the rest all use Carbon Film.

Re: DR Z Prescription Jr Review

that is a nice setup you have. i had a hard time finding od pedals thay sounded right with the RXES i had. i did like the banzai cold fusion with it though.
 
Re: DR Z Prescription Jr Review

my Z has been my main amp since I got it and I paid a lot for it when I didn't have a lot to spare :) The moment I saw it in a consignment shop and played through it I knew I had to have it. It's the very reason I don't usually gas for amps anymore (with the exception of that Shiva I tried) :) Grats on a great amp from a great builder

No FX loop on this one. You are so right about really hearing what the particular guitar sounds like, this amp picks up everything.

That is why you are the "Gearjoneser"! LOL!

What is that purple pedal? Looks like it says "Shaggy Jim"

That is a Moen Shaky Jimi(Univibe type vibato pedal)

What did you get again? Z28? That EZG has me interested. I listened to a clip of Buddy Whittington playing through on for Zfest '08 and it's a thing of beauty, pure blackface tone.

that is a nice setup you have. i had a hard time finding od pedals thay sounded right with the RXES i had. i did like the banzai cold fusion with it though.
I also noticed that the Zendrive, RC Booster and Crunch Box seem to pop up in conversation on the Z forum a lot for the RX Jr.

I'm thinking that I should make another rear baffle to make the avatar cab a closed back. It's very easy and would add another dimension to it.
 
Re: DR Z Prescription Jr Review

Wow! Congrats with your new acquisition! I can believe it sounds killer.
 
Re: DR Z Prescription Jr Review

VERY nice set up..... looks very classy too. I'd like to get some time on one of those, nice one.
 
Re: DR Z Prescription Jr Review

How many watts? How's the headroom? I got very intrigued after I saw some on the ebay. It'll be a purchase far away in time (a year perhaps ;)), but I got interested now. Especially due to the Voxy clean.

It's 15w with HUGE iron so it's got some decent headroom for a 2 x el84 amp. The cleans are beautiful, very chimey and warm.
 
Re: DR Z Prescription Jr Review

i think i would have liked the rxes better if my cab had not have been loaded with vintage 30's. the WGS green beret's i put in my bogner 2x12 sound alot better with my ghia.
 
Re: DR Z Prescription Jr Review

I'd like to add the Prescription Jr. to my amp collection. I already have an '04 Maz 38, 2x12" with Celestion Alnico Blue speakers. The Maz 38, is a bit much for home use, and the Prescription Jr. really intrigues me.

Re: DR Z Prescription Jr Review

Maybe you should look in to a Rocktron Austin Gold OD...there's a high end bump that makes it more like treble booster than a normal OD...good stuff.
