Re: ESR Graphic Fuzz [schematic]
Finally, I've done the vero from Tone Report Weekly Issue 118 http://www.magazine.tonereport.com/tone-report-weekly-issue-118/0778177001457730164 Page 40-48 https://farm2.staticflickr.com/1681/25998765093_92b69d7102.jpg I've added a volume pot after the level. Sounds amazing, full and organic but th...

Re: ESR Graphic Fuzz [schematic]
Well, I thought the layout was verified, in theory works well. So, the cut under R5 it's wrong?

Re: ESR Graphic Fuzz [schematic]
Can I use the TL071? I have built the vero from tabbycat and I have no sound.
Some oscillation but nothing more. The 9v and ground are the common true?

Re: Home Brew Electronics - Detox EQ
Actually, I use a volume pedal with a treble bleed inside. Works well with my Orange amp but it's somewhat limited with the EQ, especially, switching between guitars and pickups.
The idea of the compressor is good but I can't do it with my Diamond Compressor clone

Re: Detox EQ
I'm also very interested in this pedal. I thing that the new Mad Professor Evolution Orange Underdrive it is based on the Detox EQ.

Re: Lumpy's 73 Boost
Ok thanks, or use a bipolar or a tantalum cap, true? I will try the vero from Silver Blues these days and check it...not yet verified right?

Re: Lumpy's 73 Boost
With 22uf instead of the 680nf, what is the polarity of the electro? Its the same?Nocentelli wrote:I had a play about on the breadboard, and a 'fat pot' works quite nicely, I just replaced the 680n cap with a 22uf electro, and replaced the switch with a 2k pot.zosotone wrote:Nice Mbas974!

Re: Lumpy's 73 Boost
Hi Tommy, thank you so much for your answer. I love this thing, sounds amazing. The led in this model it's white (a little bit darker) and I put a 2k2 resistor directly to the LED. Also, had a bad connection on the board. I soldered two 1M's (in and out of the board) because I had problems with popp...

Re: Lumpy's 73 Boost
The led was soldered directly betwen the 15nf and the 68k.

Re: Lumpy's 73 Boost
I added the two 1M's, on the input and other under the board on the output for the popping. I omitted the 68k beacause it's for the led resistor. Thank you for your corrections.

I added two pull-down resistors (blue in pictures).
