TomTFS Posted June 9, 2011 Share Posted June 9, 2011 I want to be able to switch my pedalboard between keyboard and bass. So two signal chains and the effects are swapped between them. Has anyone tried to do this before? Ideally I'd like a single switch and have it all as simple as possible. Had a look at the Lehle loopers and the Boss LS2 but I don't think they can do it, unless someone can correct me? Any thoughts? Cheers.

Al Heeley Posted June 9, 2011 Share Posted June 9, 2011 For about £15 and 30 mins soldering you can make a simple effective A/B pedal that will do the job. I can knock one together for you if you want. You can use them either way: one input to choice of 2 outputs, or choice of 2 inputs to one output.

I've got one keyboard going to a DI, then bass going to amp, and I want to be able to swap the pedals between the two. So changing between: Bass>switch>amp with keyboard>switch+pedals>DI and Bass>switch+pedals>amp with keyboard>switch>DI Quote Link to comment Share on other sites More sharing options...
Al Heeley Posted June 9, 2011 Share Posted June 9, 2011 so do i understand correctly? You want to be able to switch the pedals between being in between the bass + amp and being in between the keyboard + DI ? Quote Link to comment Share on other sites More sharing options...
Truckstop Posted June 9, 2011 Share Posted June 9, 2011 (edited) To get my head around it, I've drawn a diagram in my head that just involves the use of two A/Bs (assuming the OP doesnt want volume or equaliser control for each channel). Scenario 1 - bass > pedals > amp Scenario 2 - keys > pedals > D.I. > P.A. So you'd need one A/B before the pedals (bass and keys into pedals), and an A/B after the effects (pedals into channel one (amp) and into channel 2 (D.I. and P.A.). The pain in the arse obviously being, you don't want to have to click on two seperate pedals to switch between bass and keys. Looks like it's a job for Max @ [SFX]! If I've got what you're after correct in my brain! Truckstop Edited June 9, 2011 by Truckstop Quote Link to comment Share on other sites More sharing options...
Doddy Posted June 9, 2011 Share Posted June 9, 2011 (edited) Are you using the keys to play synth bass parts? If so,I'd go Bass > A/B >Pedals >DI > split to Amp/PA Keys Edited June 9, 2011 by Doddy Quote Link to comment Share on other sites More sharing options...
Al Heeley Posted June 9, 2011 Share Posted June 9, 2011 pretty sure u could wire it with a 4pdt switch which in effect works as per 2 switches working in synchrony together. This would take the 2 inputs and route one of them thru the pedalboard and back, but input a would always end up going to output A and input b would always end up going to output B.

Al Heeley Posted June 9, 2011 Share Posted June 9, 2011 (edited) this would allow either the bass or the keyboard to feed into the pedals then back to respective outputs. The fx loop would be shared but only by one active instrument + output at any one time Edited June 9, 2011 by Al Heeley Quote Link to comment Share on other sites More sharing options...

Someone suggested a workaround with an LS2, putting the FX in loop A, keys in and out on B, and bass on the input with amp on the output. Apparently it'll do what I want if set to "output select" mode. Can anyone confirm or deny this? Otherwise it's off to SFX I go. Cheers.

Truckstop Posted June 9, 2011 Share Posted June 9, 2011 (edited) Oh, you want both at the same time?! I would say it can't be done and you're a complete mentalist. Running two instruments stimultaneously through the same effects and then splitting the signal after the effects so that the bass ends up at the amp and the keys end up at the DI?! You would either need to mod all your pedals to carry two signals, or buy another set of pedals and just deal with it.

Haha, that would be some insane pedal otherwise. Quote Link to comment Share on other sites More sharing options...
pantherairsoft Posted June 9, 2011 Share Posted June 9, 2011 So…. Bass —————————— Amp \ / \ / ——FX——--- / \ / \ Keys ——————————PA Sorry about the drawing! You play bass and keys. If you play bass through FX then keys go straight to the PA, but if you play keys through the FX then the bass goes straight to the amp… yeah? I don't think the LS2 will do what you need. I use one and am pretty sure what was suggested wiill not work. I'd ask Max! Quote Link to comment Share on other sites More sharing options...
xgsjx Posted June 9, 2011 Share Posted June 9, 2011 Hmmm, tricky one. How about a 2nd pedal board for simpleness? It sounds like you need something that works like a switchable effects loop that wont cut either channel. I'd PM Max Quote Link to comment Share on other sites More sharing options...

I'd PM Max[/quote] Thought about that too, but it's just a few too many extra pedals to worry about. It's not [i]actually[/i] for me, it's for a band I work for who aren't particularly great at looking after gear and keeping things simple so I'm doing my best to make it simple really. But yea, Shep and others have the right idea now, had a torrent of people suggesting A/B boxes on other forums Quote Link to comment Share on other sites More sharing options...
xgsjx Posted June 10, 2011 Share Posted June 10, 2011 What about them using a couple of multi fx pedals? It'd be a much simpler & cheaper option for them to have 2 floor pods or similar. Quote Link to comment Share on other sites More sharing options...
Higgie Posted June 10, 2011 Share Posted June 10, 2011 Surely you could just have a box with 2 inputs, 2 outputs, and then a footswitch which switches which channel the fx loop is active on? Quote Link to comment Share on other sites More sharing options...
Al Heeley Posted June 10, 2011 Share Posted June 10, 2011 I'm pretty sure this would do it, if you wire up a 4pdt switch as follows, the send to fx and return would be common to both keyboard and bass sides of the switch, when fx is not on in bass side the signal goes clean to amp, and signal diverts to fx for keys, when u press the switch the bass signal goes to fx then back to amp, the kyb goes clean to DI Quote Link to comment Share on other sites More sharing options...

Al Heeley Posted June 10, 2011 Share Posted June 10, 2011 (edited) Here you go, get a box, a 4pdt switch and 6 mono jack plugs.
