Mid Booster

[petemoore]

thank you aron, huge help. i'll replace the pots in the AMZ stack w/ resistors and hook that to the end of a booster. will a 9v power the whole cirucit though (booster and filter)?

>>>You will find that changing resistances changes response [like a tone control] and using a pot or two might make it easier to find the sweet spots where you can set them. Bear in mind if this TC is used with a different effect, guitar, amp...the fixed settings might not sound the same.

screw whatever ive said previously, ive got it figured out. i'll use the LPB-2 circuit as a booster, and a modified big muff tonestack as a filter.  i'll try to get the screenshot/tonestack save file up as soon as possible so u guys can have a look at it and see if it will work. this will have two pots: volume and tone. the only reason i'll have the tone pot is because i dont know how else to do it. i wont ever turn the tone knob up, it will always be on 0. if anyone knows what i could sub in for a 250k linear pot that will always be all the way off, please tell me. i'll try to get the save file up soon. thank you.

the filter i made peaks in the 600-1000hz range, thats mids right? i mean, its high mid, but still mid, correct?

Look at www.morleypedals.com/downloads.html (Wah schems).

They work w/o coil inductor. The PWA-schem is a good start and can be modded to a universal mid booster (similar to the WH Tone Leper) and
the filter stage is pretty standard.

I'm far from an expert in this area, and I'm sure there's something wrong with this approach, but here's how I would do it:

- Take the LBP2 Schematic and build it on a breadboard.

- Get a few different capacitors to substitute for C1 - the stock .1uF, and smaller caps like .068uF, .047, .033, .01, .0047, .0022, .001, etc. (you get the idea - just a bunch of values smaller than .1 to plug in).  Play around with C1 until you find a value that cuts the right amount of bass to give you the frequency that you are looking for.

- After you find a value that you are happy with in C1, if you want to cut some of the treble out of the sound, you can add a small cap after C1 to roll off some of the brightness.  This will leave you with a mid-booster.

OR

If you want to control the level of bass that is being cut, you can use the same technique that is featured in Joe Gagan's Easy Face schematic.

no guys, i have it all planned out. i have the schem of the whole thing on my comp, but could anyone help me w/ a pcb image for the big muff tone stack?
