So, I'm thinking about this. I've played the old Roland VG synths years ago with the "roland ready" strat. I understand you have to think and play "like a keyboard player" to some degree - IOW, "strumming" your guitar like it's a guitar but with a piano sound isn't going to give you a very useful sound. Bonus here is I can play some keys, and know MIDI well, etc. That's been 15 years ago and even back then the tracking seemed pretty good and all the alternate tunings could be extremely useful. Just messing with it in the store after a few minutes I had the "hang" of playing it like a keyboard player (for those types of sounds) So my questions are maybe on the more practical side. 1. Roland GK3 on a Strat - looks pretty easy to install. Double-sided tape on the pickup, and the "controller" thing looks like it now just attaches to the strap button with some kind of mount. So I'm looking at "reversibility" - can I put this stuff on and then later, if I decide to take it off, it's not leaving goo or scratches, etc. all over the guitar for the controller (I realize I might have to wipe off some residue from the tape under the pickup). 2. I see some discussion about the pickup height and sensitivity. Are they pretty forgiving or are they very finicky? I play with a fairly high action. I know Roland has specs but I'm wondering if people's experiences have been that it's pretty much stick it on and it works - or will it need a lot of adjustment? 3. I was looking at the Boss GP10 synth. Anyone have it? Pros/cons, especially compared to the Roland GR55 (or whatever the current production flagship model). One thing I would like to do would be to not only play the sounds in the pedal/synth, but to take a MIDI out and play sounds from additional devices as well. The GP10 doesn't do this without going through some USB device first so that might make the more expensive Roland the better option. 4. I would basically want my guitar to be able to play my traditional guitar rig, OR the synth, and possibly combine the two. It looks like I could just take the 13 pin out to the synth, and have it's sounds go on to the amp/monitor via L/R jacks. Then my guitar 1/4" could go straight to my guitar rig as before (hmm, two cables coming out of the guitar...). I still want my "straight to amp" signal and I'm willing to bet that even in some kind of bypass mode this device is going to color the signal. Especially if you can plug the output of your guitar into the controller and then that gets passed down the 13-pin. I'm sure impedance will be messed up and there'll be no "true bypass" models or anything. But since I'd be sending to both, I'd need some way to mute each signal path. I can easily set up a pedal with the volume on zero to mute my guitar rig. But I'm wondering if it's practical to do the same on the synth? I know with the pickup, if both signals are going through you can use the "guitar/mix/synth" thing. But since I wouldn't be doing that I could turn the volume on the guitar down to not pass any guitar signal (and bring it up to blend) but to mute the synth - I think changing that button on the pickup controller to "guitar" (to not send signal to the synth, thus "muting" it) is not going to be "performance durable" in the same way just muting the system would be (can I set the control pedal to volume and make it zero or otherwise bypass the unit so it may be receiving down the 13 pin but not playing?). Thoughts?
