Re: Peavey HFD-2 Hotfoot troubleshooting (scheme attached)
In case anyone in the future sees this, experiencing the same problem, I found the solution. Being buffered bypass, there's not a pull down resistor at the input, since it's intended to always be "in circuit"...a problem when using it in a looper situation. The input is left "hanging&...

Peavey HFD-2 Hotfoot troubleshooting (scheme attached)
I have an original Hotfoot and it's my favorite OD It has developed a loud "POP" when activated, but only the first time, then it's fine as long as it's left "on", but if left "off" for 15 minutes or so, it will POP again when turned on. It's NOT the switch, which are k...

Re: Wampler Velvet Fuzz [traced]
Hello tinker,
Yes, the extra tight pot pin 2 connection to the board is for the 100n cap to ground (which the fat pot doesn't have)
Also, MPSA18 sounds really good for the fat trannie, too....try different ones to your taste (re-bias, of course)

Re: GasPedals - Dumbbell [traced]
I have built the 3-knob version from IVIark from his blog, and it is my current favorite OD. It has a certain vocal quality, especially when you dig into the strings hard....very touch responsive. I ended up with green 3mm LED's for the clipping diodes and a TL082 for the opamp. When run in front of...

Re: ACE THIRTY
I know some of you are probably eager to trace away, but I think the speculation at this point is almost more fun. You're right, and it'll be traced soon enough. Thank you for your pleasant and thoughtful insight on what you think the circuit might be. Sadly, responses like yours seem to be the exc...

Re: Himmelstrutz - Fetto [traced]
I would replace r3/6/9 (12k's) with 20k to 50k trimmers....mind the pinouts of other FET's
FWIW, I have built 2x Fettos, and the 2SK170BL is best to my ears, and the 12k is perfect....no trimmers needed.
They can be had on eBay for reasonable cost if you shop carefully.

Re: ACE THIRTY
Well, there's the BOM in one easy shot....thanks for the "capture" On the 30/15 headroom thing, yes, it's "watts", not volts.......an approximate emulation of the touch response/sag/tonal differences between the AC30 and AC15. I suspect that once the specifics of that section of ...

Re: ACE THIRTY
I thought that might be the case, but why??
There looks to be a regular TO-92 J113 elsewhere on the board (directly down from the Treble pot)

Re: ACE THIRTY
Think i read somewhere there is a charge pump incorporated somewhere in it...if I could make out the font on that IC it could say MAX1044...

Re: Wampler Velvet Fuzz [traced]
Still dont get the optocoupler switching... Seems a really bad idea from a production point of view Neither do I. :scratch: If it is for quieter switching, I just used the BJF/MP/Bearfoot method (a 5.1v zener in series with the LED CLR) and a standard 3PDT wired in a typical manner and have silent ...

Re: TO-18 transistor sockets
Personally, I build using vero and just use SIP "snap off" type sockets for transistors. Don't know if these will help you or not (if they will fit you needs) but they are certainly affordable. From Mammoth $2.80 for 36 sockets http://www.mammothelectronics.com/620-SIP36-36-Contact-SIP-Thr...

Lovepedal now does the Zen My guess is Joyo already has one in hand and will have it on the market shortly. They have the $$$ ($600 is nothin to them) and the ability, plus no fear....they'll recoup the investment in the first hour of sales to TGP'ers alone. And you can be sure it won't be gooped......
