Muff'n tubes mod

matskull · #1 06-10-2008, 10:37 PM

Hi everyone, I've searched before posting, don't worry.

I've been happy with my muff'n up to date and I still like what it does but I now got a different application for it and find it not tight enough compared to my clean sound when I play loud.
I feel like the bass knob is really hard to set in order to habe tight bass, for rythym only with less groove thiis pedal is perfect but for tighter, faster stuff it lack definition in the low and low mid.

Does anybody know what mod can be done to it in order to make it tighter and retain it's gritty /fuzzy tone?
Would changing tubes be a good option?

If it can't be done I'll still play it and buy another distortion that does what I want but when I was hopping for a destortion pedal, this one was the only one that seamed to keeps good lows and mids even if I feel like it's not enough right now.

Any input would be greatly appreciated.
Thanks

PS: I play a p-bass through a vintage svt

I don't think changing tubes would do much to "tighten" the low end. I guess I would be inclined to put it in a blender loop and roll off the lows altogether using the EQ on the Muff'n, so that the lows in the blend were just from your clean bass signal.

sorry for my ignorance but is a "blender loop" somthing I can buy or do you mean split my signal into 2 channel, one dirty one clean.
thanks

Yeah, changing the tubes should mostly change the gain range, and not so much the EQ.

Where do you keep the bass control at? I thought the bass got kinda boomy/loose if I turned it up much, but a little boost wasn't too bad with the setup I was on.

And yeah, a blender loop is something you can buy... it lets you mix in some of your clean signal, which is a little like splitting things into a clean and dirty.

to keep with the original spirit of the question, you might try changing out the first tube with a 12AU7. it's lower gain, might bring back a touch of tightness, and with the 12AX7 in second position it'll still give you access to much of the grind you love.

just an idea. not even sure if it'll work. but 12AU7's are pretty cheap, so you might just try it. let us know.

I keep the bass knob at about 10 oclock, mids between 12 and 3 oclock and hiah at 12, gain at 3 oclock, volume to match the original clean volume.
I might as well just go out buy a couple of tubes and try thoe by myself, I'd just like to know if anybody tested that kind of stuff.
It sounds tight at lower volume though, not s tight at high volume while my clean stays tight....

I presently only got this pedal, I wanna make it as good as posible, I might buy some other at some point though, I'm forming a rock drum and bass right now so I'm thinking about how to get the coolest sound out o what I have.
I presently have one vintage svt through vintage svt810 plus a svt-vr through a svt810e, I might sell the svt-vr...I dunno yet.
I could use both channel on a single amp to blend clean and overdriven tone, I could also add a synth/octaver on one channel or on the other amp with an a/b/y box...
I don't have an a/b/y box for the moment though but let me knw if you got some idea.

The two rig thing would be cool but not so pratical to transport....

thanks

Did anyone tried to blen the muff'n with their clean signal?
I'm really interested in trying it but right now I don't have an aby and I had phase issues when I tried it using the "lead jump" trick.
I'd really like to hear what your experiences were.
thanks

I use the muffin in a blend loop. seems to work fine, no phase issues that i can tell. Lead jumping (i assume) refers to passive blending and will cause a feedback loop. My muffin doesn't work in a feedback situation. Seems to be phase (?) problems. But the blend works fine.

Allright good to know, when I said lead jump I meant pluging my bass in amp A normal input, then pluging bright input to amp B normal input, with the muff'n between both.

Do you think I'd have phase issues with an active aby box?
Cause that's what I'd like to do eventually.
thanks
