Re: Amptweaker - Tight Metal [traced]

I made a version this week on veroboard using this layout: http://guitar-fx-layouts.42897.x6.nabble.com/AmpTweaker-Tight-Metal-td9212.html And I’m not having any volume issues, it seems to be about the same as most other preamp pedals I have (ISP, AMT, etc). I guess you could compare that layout to ...

Re: Diezel VH4 Pedal [schematic]

I finally got around to building this pedal on Bugg's PCB. Great pcb as always, sounds great and works perfect.

I used the requisite TC1044SCPA and its silent, no switching noise.

pictures attached.

Re: Fortin - Grind Pedal

Anyone built the vero version? Mine works "okay" - all pots are doing what they should do and the preamp is amplifying the signal. But i got quite some high frequency hiss when turning the treble up (tested with different power supplies and battery the behaviour stays the same). Any ideas how to im...

Re: AMT - Legend Amp Series 2 [traced]

they were designed for 9v dc - phatt is spot on with his comment - use the correct voltage for the correct response I was wondering this also, I like to experiment with different voltages, and often pedals will function differently at higher voltage. I can understand how some wouldn't like that cha...

Re: Fortin - Grind Pedal

I believe you guys are right about the grind/33 being a TC Electronic integrated pre clone, makes sense :thumbsup nice layout & scematic here.. http://www.rullywow.com/wp-content/uploads/2015/05/ChuggaPre-v1.0.pdf Yes, I hope there was more pics of the insides of the Grind/33 to identify the cap va...

Re: Fortin - Grind Pedal

My original TC electronic integrated preamp has a UA741 in it. There's another schematic floating around that specs a 741. When I built a clone of it, I couldn't hear a difference between a 741 and a TL071, probably as the integrated preamp shouldn't be clipping the op amp, and it's not like guitar...

Re: Friedman BE-OD Pedal [traced]

I got Bugg's PCB the other day, real quality board. I like how symmetrical the layout is. I both love and hate how compact it is... It looks great and I'm glad it fits so well into a 125b, but that compactness does make it a bit harder to work on. No big deal for experienced people but I can still c...
