Help Modding A PW-2

[tomhanzo]

I have a Boss PW-2 that i need help modding. It is amazing sounding, but loses my low end. I know pedals like the DS-1 just need a little resistor changed to fix this. I'm not good at circuit stuff at all, but i can work on pedals with an iron. I found the schem for the pedal.



Can anyone help?

bump. please?

I dont want to have to find a DIY forum and create and account just for this.

It's not a resistor usually, but rather a capacitor either at the beginning or end of the chain that gets swapped out to let more bass through. See that 47nf cap near the beginning? You could try swapping that to a bigger cap, like a 470nf or 1uf. All of the other caps in the signal chain are 1uf or bigger, which is plenty big enough. Hope that helps.

Well could i just put a solder blob in there to bypass the capacitor?

Not recommended, it's there for a reason! Without it that +4v supply would try to flow to ground through your instrument.

Just a suggestion, but instead of modding the pedal consider getting a loop blend pedal with blend to enable you to mix the effected signal with the dry signal. This avoids possible accidental damage to the circuit.

Easiest/cheapest is a Boss LS-2 off the 'Bay. New I've seen 'em for 80 bucks including shipping, used around 40-ish or even less (WARNING!: I am turning into a bit of an LS-2 fanboi over the last couple of months). Damn good bang-for-the-buck in my opinion. I like the LS-2 'coz it does a bunch of handy signal routing stuff, not just blending/fx loop.

There are a bunch of other companies that make specific loop/blend pedals with varying features...

Unfortunately, although Barge Concepts stuff is excellent (I have a GLZ-1) they haven't answered any of my emails in the last month and their website has been "under construction" for quite some time so I'm reluctant to order and pay for anything from them at the moment.

Well i have had a couple things on my mind. I cracked the pedal open today and they are super packed in there. I dont even want to try to change the cap out for another. I have a schematics to put a blender in the pedal. I haven't decided which i want to try.

Blend Circuit

I may just build the circuit and see how big it is first. If its too big i'll make it into a pedal.
