Wiring resistor to compressor input

[bongomania]

The funny thing is, that "almost overdrive" sound is one of the things l particularly like about Orange Squeezers.

...if 4.7k is too mild, what might be more suitable?

A resistance equal to the one that's already there would cut your input in half - I'd say that'd be a good place to start.

I haven't looked at the schematic, but I'd be afraid that could change the way the circuit works (is there a high input impedance buffer after the resistor that's already there?); else you could replace the one that's there with one that's half the value, then add another - for a total resistance that's the same as it was. That might be the safest bet.

Half is way too much if you ask me, it would stop compressing!

i got a set of 470k resistors.

Better? Maybe?

That's only three decibels, Dude.

I think the unfortunate thing we're learning here is that the only way to determine the value needed is through experimentation- and our poor protagonist just wanted to hand the box to a guy he knows and say "solder the resistor here".

Opivy, I'd say just pick one, have the guy solder it in the place I described, and hope for the best. The only other option I see is if you bring your bass and amp with you, and bring the soldering guy a 6-pack and a pizza, and convince him to spend the afternoon with you experimenting with different R values.

I used the 470k resistor and had the guy install it.

works flawlessly. I had to turn up the compression trim pot a hair is all.

Thanks for your help!!!

Ah, good!

three decibels is still half the power no matter how you look at it.

In terms of voltages it's actually -6dB. Since the threshold detector is likely to be voltage driven I'd say it's likely to be too much.

Recall that the OP's problem is slight, occassional clipping.
