I've been looking into the Roland GR-55 guitar synthesizer and decided that I want one, but I was wondering if I need to buy some kind of PA system to go with it or if I can just use it like I would use an effects pedal?

GR-55s are not really guitar amp friendly, in fact they do not recommend using one. Most people plug the synth portion into a keyboard amp or a PA type of rig.
If I miss one day of practice, I notice it.
If I miss two days, the critics notice it.
If I miss three days, the audience notices it.

you could probably use it with a guitar amp, but you can get much more creative with it.

it seems to have a direct guitar out, which i would plug into a guitar amp. but the synth outs i'd probably plug into a keyboard amp or a power stage monitor, so i have the full range response for the keyboard, synth and bass tones.

You can use it strictly for guitar tones by removing the cab sims and such, but you'd be severely limiting the versatility of the GR55. Use it in a full range or straight to FOH type system and enjoy!

Normally you'd run the synh section through the PA but good things can happen for certain applications. Deep Purple's keyboards sound is a Hammond running through a cranked plexi.

Well I wouldn't wanna lose those synth tones it's one of the top reasons I want it. I've never really heard of PA systems before are they expensive? Also would I still be able to use it in a band setting?

The cheapest way for you would be a powered PA bin. You don't really need a full PA, just the power amp and speaker which is what a powered bin is.
My keyboards rig is actually a rack line mixer, a 1000W per channel PA amp and a couple of 15" Laney bins loaded with humingous JBL drivers. You don't need anything like that, a decent powered bin is all you really need.

I'll definitely look into those, but I'm starting to think that at this price I'd be better off buying several different effects so now I'm a little torn!

I came close to going the guitar synth path myself but instead I decided to learn how to play a keyboard instead.

I'd do that but my main focus is guitar if I'm dropping a decent sum of money it's gotta be toward that

You can often pick up used PA gear stoopid cheap. When guys retire from gigging it's the first thing they sell off. Watch the used market for a while and see what pops up. Try to get something in the 200W range and preferably with a 15" driver.

Even if you don't go the guitar synth route it is always a good idea to own some PA gear, even if it's just a decent powered wedge.

Same, though I might get one if I ever have money to throw around easily.


Does an acoustic amp have a flattish response or is it designed to make acoustics resonate the best they can? I imagine they have a better response than a guitar amp for a guitar synth, not cutting off the highs so much.
