Jfets in Supreaux

[petemoore]

I thought I was getting some J201's in later this week, but they arrived today!!! Thanks Aron !!
 So I had to build a Supreaux, the build went fairly easy, about 2.5 hours.
 I used alot of sockets where there are the back to back caps, and the 'to ground' rollloff caps, and used two 1megs to substitute for the second 470k.
 Took me about 10-15 min to find a couple places I didnt' finish wiring, [for those taking numbers].
 Then it was on to the fun part of dialing in the Fet's.
 Amazing circuit, sounds alot different than the ones I've been using...more amp like...between switching caps [pulling or changing values] and the tone and other controls, I was dialing in some great sounds.
 Playing "Take it Back" and 'Love Me 2 times', the low end chord grind was smooth WITH  the pull offs and hammer ons at the high end of the chords ... definition, tone, dynamics all very good...
 I used J201's for all three transistors,..with guitar vol and gain pegged, was going to a 'squash reverse compress' type thing [like an overloaded amp] when hammering low chords...real cool...probly had the gain set 'too high'... :lol:
 Guitar volume cleanup...very nice gain reduction, I could go from bell like tones to nice grunge OD by varying amplitude with picking strength.
 Quite the impressive tibe amp like Distortion, definitely adds character, easy to get from here to there [mild OD to tube grind tone was easily workable using 3SC pickups]...gave the guitar new, well thought out sounding multi faceted attitudes.
 Works Great !!!
 Thanks to the guys at ROG for this and all the amp emulators...I still have 17 new J201's

How are you using this pedal? Are you driving a power amp alone or using it in front of a preamp?

Good question...[I wrote a review on the Supreaux], WOW...
 During testing/tweeking, I used an RCA Victor Phono pre-amp and amp [removed from console stereo circa 60's?], using 3SC pickups for source. As soon as it lit up..
 I added a switch and caps mod to the two rollof caps at the output by the 12k's, bypassing the socket for the signal path  half of each cap, I can easily eliminate one or both by pulling them from the socket, or solder a different value to the end of the wire coming off the switch ...very nice, I'd call it a tweekable  Bright/Dark switch, this and the TC work great. Using the switch is like going from bright to normal channel on a four input amp, great for bright boost lead use.
 Then it went upstairs to the studio where the Dyna ST 70 Power amp is used. stereo 7199's into EL34's [each side], 'Clean and Normal' describe it well, but superb could also apply. That into 2x12's [same ohmage...lol..'one's a Fane].
 My educated guess is that the Supreaux should be pretty 'amp friendly', simply because it is tube amp like and smooth, and has a comparitvely wide tonal range compared to say a FF or Dist+...not that a FF doesn't, but FF has a rep for sometimes being amp-picky.
 Though I have yet to try it through the vintage-reissue MkII Marshall... :twisted:
 Edit...just ran it through the MkII, but not high volume, will probly be even better with it cranked a bit [it seems to like that], goes to hard grind OD, but not heavy distortion, It's a tube amp emulator...Real Sweet, with a TS, Booster or Comp in front it breaks up really nice. Super good from Boost to Heavy OD. Seemed like I was getting heavy OD from just the S and the RCA amp, only had it a day now...still getting used to it, definitely a keeper...it won two stomp switches, a nice roomy box, and an indicator LED...
