A/B Amp Selector

Hoody · February 13, 2014, 01:17:14 PM

Does anyone have any experience and good recommendations for an A/B selector switch? I'd like something I can use to select between 2 channels on an amp, and also something that could select between two different amps. Something quiet that doesn't suck any tone.

thanks very much for the input.

Lehle is very popular, Radial has a good rep too. I think both of those companies make buffered AB (or ABY) pedals. You shouldn't get any tone suck with an AB switch through, really (unless it has a crappy buffer, but I think most are passive true bypass or intentionally have a good buffer). But if you use the Y setting of an ABY, you want to drive the signal before it splits (meaning you want the pedal to have a good buffer).

The only one I would stay away from is Morely. With AB and ABY switches if there's more options, the better. Phase issues between the two amps can be a huge pain but a good ABY will have options to correct it with a ground lift.

Good point about phase, but I think a ground lift fixes noise and a phase invert switch would fix phase.

Right

The Fulltone ABY is another one to check out, too.

I've used the Lehle one, and while it's kind of expensive, it works really well.

For something a bit less expensive than the Lehle (great product) is the Radial Bigshot. It has options for phase inverting and ground lifting. Could be what you're looking for?
