Question about Roland Gr33 Guitar Synthesizer

1 Answer

Guitar out has no sound

Guitar is connected to the GR33 using the unit's cable connected to the pickup installed on an Ovation Legend. The mono out on the back of the unit delivering the synth sounds to a mixer works fine, but the Guitar Out on the back of the unit produces no sound, no matter what I connect it to.

You must connect a short jack cable between the GK2 or GK3 and you normal guitar jack out. Secondly, the switch on the GK should be in the middle, that will give synth & dry guitar simultaneously.

SOURCE: ROLAND GR30 POWERS UP BUT DOES NOT MAKE A SOUND

Make sure you use the ORIGINAL AC adapter with the unit. It takes a 9VAC one.

The adapter for the GR09 will NOT work and will act the way your unit is acting.

How do I connect my roland piano 5500 to an amp


On the rear of the piano there will be two 1/4" jacks labeled Output Left and Right. One will be labled Mono as well. If you are using a stereo amp, use both, and if a mono amp use just the mono output. If your amp is a guitar type, connect a shielded cable with 1/4" phone jacks such as you'd use with an electric guitar from these jacks to your amplifier. If you are useing a home stereo amp, you will need a cable with 1/4" phone jacks from the piano to RCA phono jacks on the amp end.

Buzz coming from elec. guitar pickups only when using Aviom and headphones


It is a definite pickup grounding issue causing hum/"buzz" which diminishes when touching strings. Check the impedance of cable jack inputs and cable which should be 1/4"mono input/output jacks) . A personal preference but effective is to NOT run guitar direct into mixer but through an external amp w/ a headphone out jack . Noise gating/preamp filter also will help eliminate the "buzz"/noise from pickups. It is unfortunately the nature of the "electro-magnetic" beast when it comes to electric guitar pickups .Hope this helps.

I have an Ovation Celebrity Koa with the OP-30 system in it. When I plug it in, I don't always get sound. I changed the battery, and have a new patch cord. Can someone help me?


where the socket is for the cord to be plugged in, often the ground will come loose or break on the socket connection, you will need to take off the plate that conceals the electronics of the guitar and see if any wires have become damaged , this happens a lot when your using a patch cord with a 90 degree end going into the guitar , it puts added pressure on a already touchy socket.

Getting hum through the speaker but when i put my hand on the jack socket it stops


If you are in the US, take a length of light-gauge wire (AWG 20-24) attach it to the center screw that keeps the cover on over the standard dual AC receptacle and to a screw on the back of your unit. This kind of problem often is caused by a poor grounding of the cover or chassis.

My s5470 does not sustain well at all.also,the bridge pickup sounds ok but lacks ''attack'' in upper register.great guitar otherwise.i use a peavy 5150 60watt amp.


I personally use Seymour Duncan Humbucker pickups, and have never been disappointed. You might want to take your guitar up to a music shop and try it on different amps to see if your amp is your problem, or if it is your guitar's pickups or wiring. You could also try adjusting the height of the pickups until the sound you are looking for is achieved. I have also had guitar cables make a big difference in the sound. Make sure you have a good set of cables, and you may want to adjust the EQ settings of your amp to make up what the guitar lacks.

Parker fly acoustic pickup quit. When the red button is depressed all my gain is gone from the magnetic pickups and from the acoustic pickup.


If you are using a mono (2 contact) guitar cable then the output from magnetic & piezo pick-ups should be mixed together. If you are using a stereo cable (3 contacts - tip, ring sleeve) then it will be stereo with one signal sent down each core of the cable with common/ground on the sleeve.
If you are using a stereo cable into a mono amp socket it is possible that a short is occurring, which would cut the signal. I would also check your cable for poor/ shorting connections. The signal level could also drop if the pick-ups were out of phase with each other.
For more information on balancing the levels between the pick-ups see the user's manual here

I my gr 20 is only picking up e a d g b and not the last string ,is there any way i can test it to find the fault please thnk you


If you want help from Roland you will have to register:http://www.rolandus.com/backstage/login.php That will get you access to full support and their email address. I think you are having problems with your GK-3 pickup. Make sure your string that you are having problems with is the optimal height etc. The adjustment for the GR-20 is in the manual at this link:http://www.roland.co.uk/assets/media/pdf/GR_20_Q_A.pdf Make sure your pickup is installed correctly and adjusted properly first. The manual is here:http://lib.roland.co.jp/support/en/manuals/res/1811530/GK-3_e11.pdf If you have everything adjusted and only one string is not working then I would guess you have a cable problem and the best thing is to contact Roland for advice. I didn't walk you through the adjustment because every installation for every guitar is different. Hope this helps.

No sound


You would NOT use a stereo cable to plug in your guitar.

The stereo cable would carry the battery voltage back to the amp and MAYBE cause the fuse to blow.

You use a MONO instrument cable for your guitar.

The ring connection is use to complete the circuit to turn on the battery in most guitars.

Replace the fuse ONCE and get the proper instrument cable (NOT consumer audio cable) for your guitar.

If fuse blows again, take amp to shop for service.

Epiphone BB King Lucille guitar treble pickup in mono mode


Realize that when you plug into the one jack it disconnects the fingerboard pickup from the mix.

DO NOT USE "stereo" cables as it is intended to use TWO MONO cables, one for each side of the stereo.

IF you plug into the one jack that will connect to the bridge pickup, it will disconnect the fingerboard pickup from the mix BUT leave the fingerboard on its own jack.
That same jack will have BOTH fingerboard and bridge pickups IF the second jack (bridge) is not plugged into.

This is according to the schematic. If you find that yours works backwards, then either the schematic is wrong OR your guitar pickups may be electrically swapped.
