I've modificated "Hao Sole Pressure"♪ It's a handmade model,so original model is enough to play. But it become better by my modificate!
I said original model is very good enough.The parts are very few, but sound is straight and fat.
I thought it was no good to modificate such a good pedal, but I couldn't control my libido!
modification menu is here 1.voltage up to 17v I used to do same thing on my similar pedal,pump up is very good. 2.add range selector This pedal has too much low frequency,so change capasitors and get more middle. 3.add clipping selector It has LED clipping(Symmetry).I add Ge clipping(asymmetry) and no clipping mode.
This is a finished photo.
Charge pump unit is beside 3PDT switch.It makes 17volts. I forgot to say my pedal is old model and it has no DC jack. so I add DC jack.
Near the PCboard,there is a clipping selector units. Original LED clipping is enough good,but no clipping is more! Ge diodes are 1N60.But they are no good.I'll change them. (finally I sellected 1N4148 asymmetry)
range selector works very good.Low range became tight and nice. However still has more low frequency than TS-9.
I packed many parts and there is no space in the case.
I used Belden Wire in some place,like adding units, but didn't change original Wiring materials.
This is the DC jack.Original pedal has no ripple filter.
By the way,I changed many parts on the board. I changed values Caps or Registores ,but changes are little.
ok,it's sound is…awesome! I think I'll sell it but ...no,I can't!
sample sound can you recognize differ in two samples?
