Re: BAJA Real Tube Drive pedal project [verified]

In adding a tone-stack to this pedal, what should fit as the best solution ?
A solution like BB-Preamp can be a good option ?

Any suggestion ?
Thanks is advance.

Re: Kay - Fuzztone (F-1) [schematic]

If you are attemping to reach The edge tone better using 2SC945 (as the original unit use...),
but you should reach a good fuzz too using any other TRX.

low volume.... did you double check the pinout of used TRX ?

Black Box Buffer [schematic]

Hi this is a buffer box from Italian brand. Really good quality assembled pedal. Buffer circuit nothing really new. What surprise me is the IC2 of TL072 used for LED purpose. I do not think audio will benefit of this use of the other half IC, can someone explain it ? a double check to schematic is w...

Ok resurrection..... :blackeye

Sabro Layout is showing Treshold Pot leg2 goes into IC1(+)IN and leg3 goes into IC2(+)IN
while
ValveWizard schem leg2 and leg3 are shorted

is it a MOD ? or a mistake on Sabro ?

Re: DC regulator --> getting too hot

Thank you both guys.

Putting a resistor between transformer and regulator will drop some DC which value should be appropriate in this case?

DC regulator --> getting too hot

I've built a 220VAC -> 9VDC adapter for my stomps it's simple standard design using 4 diodes 1N4001, regulator 7809, 470u cap before the regulator and 47u after, using Hahn Transformer 10VA 230V 2x15V 2x333mA (using only 1 onf the 2 output). It's working, and I plaied for an hour... but the problem ...

Hi Fender3D, thanks for the reply... D4 and C5 are out as per Current Lover assembly guide (I'm using MN3007) : Power The MN3007 and MN3207 have slightly different power requirements. The MN3007 can operate for up to 15vDC. The MN3207 supply voltage needs to be clamped at around 8v. MN3007 – Omit D4...

Re: SoulSonicFX - Stage Overdrive - The Klon Killer!

I believe the sound of a pedal is a combination of several things...
can you tell us something more on capacitor types that you used in your build ?

C8 C9 C10 are bipolar ?
C4 C7 are WIMA ?
and the rest SMF (except the ones in 1044 network) ?
