Very cool in a trio band, esp. with arpeggio's

By Toni

We use the GR 33 a lot in our band GAP. It's like the fourth bandmember, so we call him Gerritje.


Sweet Synth

This Synth has some totally cool sounds. It's one of the most realistic sounding synths I've ever heard! It is a little pricey, however. So if you can afford it. IT'S A TOTALLY COOL SYNTH!



By Ariel-Q.Spn

Absolutely the best synth I have played as far as functionality and sound... It has almost unlimited sound capability; especially when applied to a separate midi device or synth module. I feel I should also mention that the manual provided is the most informative and easy to follow I've read. It really explains each detail of the synth. So I would definitely suggest the gr-33 to those beginners who are not accustomed to making patches and working with midi.


GR-eat Fun

By Kaffeen

from Gainesville, FL

This guitar synth is extremely robust and produces quality sounds. The presets are OK, but when you start playing with your own patches, that is where this product really shines. This is great for recording or jamming and it will take your creativity to another level. I use this at home with my Boss Loop Station and come up with some great sounding loops to jam along with and improvise to. As for recording, I am a one man band and this is the key to the magic kingdom.


Best guitar synth I've played

By IronMan Mike Curtis-lRD1.

from North Hollywood CA

There's definitely a setup and learning curve. I had to edit some patches to my taste and style. Pay your dues and the GR-33 will pay you back many times over. Generally, a more precise picking technique is called for, but some sloppy techniques render some nice sounds. I love the organs and pianos. Makes me sound like a real jazz keyboard player. Soft string pads can make a lush background for guitar chords. You can transpose individual strings for instant synth OPEN TUNINGS! The 13 pin cable can be damaged if pulled hard, so be careful, and get a spare.


GR 33 knocks it out of park


from Houston, Texas

For effects and creating unique and dramatic sounds, I have not played anything that even comes close to the 33. If you enjoy taking a guitar and creating sounds and patches that will move you to whole new level, you can't beat this synth.My hats off to MF for a smooth transaction and quick delivery.

For home studio guitarist who cant play keys, this is your Holy Grail.


This is the best Guitar Synth yet!!

By The Legend-4gxWJ

from Miami

Dont hesitate to buy this,,,what a blast to play piano and brass,,all the presets are usable and with a little tweaking,,you can have some "new patches" that sound even better. Great studio machine too!! Just play the patches as the real instrument should be played and you will turn some heads,,you will see!!


Tracking needs to be adjusted

By Curtclan

My GK2a pickup came factory installed in my Ibanez RG series guitar. When I first got the synth I had tracking problems. I would play a note and it would not play on the synth, or the wrong note would play. This drove me crazy. However I was able to fix the problem in 3 ways. Now it works fine. First I changed the gage of my guitar strings. I went from 009 to 010. Next I raised the GK2a pickup so it was closer to the strings. Finally I found hardness settings for string plucking for each patch. I seem to have a light touch. These things fixed the tracking, but once in a while I will get a delay from the time I hit the string and when the note is played. This takes a little time to get use to. Over all the sounds are incredible. even with my slight tracking problem. I would say this is worth every dime I spent on it

Your in the studio needing a keyboard player that may cost You Fifty an hour. With the GR-33/GK-2A there's no reason to need one! The Hammond B-3 preset is so realistic,that You'll think Keith Emerson is there with You!
