rust_relic Posted March 24, 2011 Share Posted March 24, 2011 Can anyone else help? I've got an old WH4 Whammy (my first one I bought 11 years ago) and the expression pedal is worn out so it doesn't stay up anymore. I was going to stick it in my rack and try and control it from an expression pedal plugged into my Rocktron All Access and controlling it by MIDI I have an old Bespecko Expression pedal (similar to the Line 6 EX1) for my Line 6 and that doesn't seem compatible with it, I have also recently got an Ernie Ball Volume Pedal Jr 6180 with a Stereo-Mono Y Lead and that doesn't seem to work properly either. If I have the Whammy on up 1 octave and pick an E note with the pedal back and then push it al the way forward it will go from that E up to about D# so won't go all the way up to the octave, doesn't matter what I do when trying to recalibrate the Whammy Don't want to keep buying and selling Expression Pedals until I get it right, does anyone know which pedals will work please?

Don'tPostThePear Posted March 24, 2011 Share Posted March 24, 2011 i think the molten voltage guys will have something for you they even willing to burn custom firmwares on their chips edit: disregard this, i though you need some external pushbutton style control pedal btw due to the mechanics of these pedals, i think they can't really utilize the pots full travel Link to comment Share on other sites More sharing options...
rust_relic Posted March 24, 2011 Author Share Posted March 24, 2011 This is basically what I am looking for If Matt has used this system with an identical Rocktron to mine for 5 years then I know it can be done, just have to find the right Expression/Volume Pedal that works Link to comment Share on other sites More sharing options...
JimboMansonMB-1 Posted March 25, 2011 Share Posted March 25, 2011 I use just the standard 25k volume pedal. Now, I don't have my Whammy racked or anything, but it works fine as an expression pedal and I've always heard that it's the best of the EB pedals for this sort of thing.

cheddatom Posted March 25, 2011 Share Posted March 25, 2011 Just buy an EB one if it works for Matt! Are you trying to calibrate it with the new EXP pedal? If you calibrate it, it shouldn't matter how far the reach of the EXP pedal is. Link to comment Share on other sites More sharing options...
Neil. Posted March 25, 2011 Share Posted March 25, 2011 Didnt matt use a liquid foot controller? Link to comment Share on other sites More sharing options...
rust_relic Posted March 25, 2011 Author Share Posted March 25, 2011 Matt had a Rocktron for Absolution & Black Holes & Revelations Tours, now using the Liquid Pro on the Resistance tour http://www.musewiki.org/Guitar_effects Mine has a 250k pot so I'll try one with the 25k pot Thank for your help guys!

Neil. Posted March 25, 2011 Share Posted March 25, 2011 eh.... that's 1/10th of 250k. You'll get some strange tapering. I'd be inclined to suggest a good midi controller tbh. Link to comment Share on other sites More sharing options...
Don'tPostThePear Posted March 25, 2011 Share Posted March 25, 2011 i think the value of the pot does not matters because it acts as a voltage divider the taper should matter, with digital stuff like the whammy i would use linear taper because that makes sense but maybe the engineers @ digitech calculated the use of log pots into the whammy control voltage slope or whatever is it called. i don't know anything about expresion pedals coz i have never had any but i think they should use linear pots and only volume pedals should use log pots.

Neil. Posted March 25, 2011 Share Posted March 25, 2011 from google, it seems any midi foot controller will suffice for the whammy Link to comment Share on other sites More sharing options...
rust_relic Posted March 25, 2011 Author Share Posted March 25, 2011 this is borrowed from musecasters, showing Matt used a Stereo 25K pedal plugged into the back of his Roctron but not sure why it is only wired from one output, I thought with Volume Pedals you have to use a Y lead Looked into it and one of these is £190, might as well buy a new whammy instead!!

Neil. Posted March 25, 2011 Share Posted March 25, 2011 how much is a behringer cheap as chips midi foot controller? Link to comment Share on other sites More sharing options...
rust_relic Posted March 25, 2011 Author Share Posted March 25, 2011 Thanks but I'd I'd rather stick with the Rocktron as it's much more versatile than the Behringer, able to have pedals and effects as Instant Access, not just programs Link to comment Share on other sites More sharing options...
tomrulez Posted March 25, 2011 Share Posted March 25, 2011 FCB1010? About £100 and I swear by mine, awesome bit of kit once you figure out how to program the thing. Link to comment Share on other sites More sharing options...
Flump Posted March 25, 2011 Share Posted March 25, 2011 I'd suggest a boss FV-500 (I don't remember if i have the high or low impedance) I like mine 10x more than the Ernie Ball footpedals. I can't stand the string that the Ernie Balls use. I currently use 2 of them with my all access to control a ton of stuff with my axe-fx. Link to comment Share on other sites More sharing options...

Flump Posted March 25, 2011 Share Posted March 25, 2011 Thanks! If you do end up going the boss route I'd suggest you buy 2 separate cables for it. You can do an 1/8th inch stereo on both ends into the "pedal 1" jack of the all access or you can do 1/8th inch stereo (all access side) to 2 1/8th mono jacks to plug into the input and output of the pedal. I do it the second way because it seems to give me better results with the sweep of the pedal. Link to comment Share on other sites More sharing options...
Impulse 101 Posted March 26, 2011 Share Posted March 26, 2011 This is my board. The Boss FV-500H pedals are hooked up using insert cables (TRS to dual TS 1/4" Jacks) they run anything in my rack that accepts MIDI CC messages. It's very easy to set up and the Rocktron pedal works in exactly the same manner. Get any decent volume pedal and it will work pretty much regardless of the impedance of the pedal. Taper makes a difference, but only a slight one as it only affects the throw of the pedal. JT Link to comment Share on other sites More sharing options...
