Roland GP-8
I just noticed that 3 people were waiting for an opinion, but I do not think qqun was still interested in this ancient ...

The G-P8 is a multi-purpose 19 "rack.

It allows to chain the following effects, in the order given:

1. Proactive and filter (type "envelope", creates a lightweight auto wah)
2. Compressor
3. Overdrive
4. Distortion
5. Phaser
6. 3-band EQ
7. Digital delay
8. Chorus Digital

There are quite effective, but I would note the lack of reverb, that would be really welcome!

Level connections:

- 2 inputs (one front, one on back)
- Main output (stereo) format Jack
- Line Out (stereo) format Jack (different impedance)
- Send / Return to loop effects
- 2 mono outputs for controlling other devices (changing channels on an amp for example).
- MIDI In, Out and Through
- Entry for the floor controller Roland FC-100

It is possible to connect the GP-8 between the guitar and the amp or the effects loop of an amp (which I do myself).

Level memory, it has two groups (A / B), each of which contains 8 banks of 8 presets.
2 * 8 * 8 = 128 presets in total.


The configuration of presets is fairly simple, with the knob on the front.

We choose a preset, you activate the desired effect, then looks at each parameter of each effect. The parameters are conventional, except for the dynamic filter is not easy to master, but not very helpful either.

To order the GP-8, it is obviously a foot controller. Evening a Roland FC-100 that plugs into the specific entry Roland or any controller noon. With a program change, we choose the preset you want. It can also control the overall volume as well as the parameters of an effect with one or two expression pedals through Change Control.

Regarding the manual, well it must already have it. Roland is always 0 in customer service, ask me, I have the manual in PDF format. It is clear is sufficiently complete to understand how the device is used.


The sound quality of GP-8 is not the best ... But we are dealing with a device of 1989! So should not ask either. I had bought for OCCAZ for next to nothing, because I needed an effects controllable by MIDI. And for the price that I paid, it was worth it.

I use it in the effects loop of my ENGL Powerball. I play with an ESP LTD F-200.

To give a little originality in my songs, it's fine (I use the chorus, delay, phaser, a little equalizer). For distortion sounds, I use my amp gain, of course. Distortion and overdrive effects of GP-8 are really ugly, do not use it a massacre. The dynamic filter is nice too, it allows for a slight wah. By controlling the Q or frequency cut with an expression pedal, you can have a pedal wahwah poor quality, but it's cool to get started.

If you want good quality effects, go your way. When I have money and the need for good effects, I'll invest in something more robust qq (tc electronic or Rocktron).


I use it for a year now.

The nice side is the price. I do not really see why all the old stuff to buy (except maybe to play the "vintage"). Buy only if you can pay you nothing else!

Finally when I have the means to make new effects, I will put my GP-8 in a display case!

Nothing to add to what has been said before on this point ...

ah, yes! ... it is the only multi-effects built as an assembly of pedals boss on the same circuit, not a complete emulation by a single DSP, as now.

suddenly, rub shoulders and digital delay effects if not zero analog (as opposed to the DSP 16 where everything is digital ... and poop!).
in my opinion, there are still things interresting bcp (including distortion!), but you need a speaker simulator behind any (even in the ordo for example).
he deserved as a noise gate on some patches and a reverb.
Finally, its presets are 80 years ... and they is not everything (including metal disto not really present).
to cheap, it's still useful sometimes (stud, including loops or synthesizers).
on stage or in the first purchase to versatile a. .. more versatile! ... tj but not as "dynamic" (I find that some existing multi-effects are the "imitate" a little smoother ...).


Everything is simple (as it is aligned pedals).


The chorus, the delay is not bad.
some distortion too.
is a device that can be creative in stud, including the hijacking, and which may please those who make the eighties revival.

the sound quality is not zero but does not necessarily satisfy those who seek its current and versatility (and whammy effects, dunlop wah, amp simulations, harmonic intelligent, etc ...).
and it lacks a noise gate ...


Given the price at which one can Toper, it can be fun ...

I bought the pedal f 7500, at the time.
at the time was a killer and I do not regret my choice.

What do you want me to tell ...
it still has a pretty face in a rack!
come on, like ... j'mets October 1 !!!...
hey hey ...

For 145 is present! I own a pedalboard with since 1988 and confirm that it is simple but effective, beautiful chorus, delays interressants, and for the era, 2 outputs for external controls including one that I use to trigger my rotosphre all out on a twin tone Koch + extension 1X12 Celestion Vintage 30.
by expression pedals control of all parameters! I personally failed to sell but I reflchi and is still one of my racks. The distos if they work well with a little chorus and delay are not ridiculous, and also make some good crunch sounds.
When the foot controller is very practical and robust. I've never had trouble with this equipment since 1988 and the battery is original. Therefore 145 is a bargain. pondered guy!


It's a breeze.


Chorus and delays and compressor TB


Value for money TB

Multi-effects rack


technology is analog except the delay and chorus are analog

Stereo Output
effects loop (I think)
Expression pedal jack
the connection is complete. I insist on the presence of the effects loop that is too often overlooked on the current multi-effects


Very easy to use as the pedals boss made the chain.
facilitates the display is very clear
the manual is basic but sufficient. some gems from the Japanese translation :-)
The expression pedal can be assigned to any of the parameters.


I use a fender princeton silver face to be 1978 and a telecaster
Contrary to what I read in another review, the sounds are very good qualities. the multi-effects do not meet current standards in terms of sound, but offer the bare necessities for a guitarist in his basic parameters are adjustable choisis.le GP8 would leave a lot to the sound of the pedals boss of the era . the overdrive is pretty good on a tube amp, nice chorus, compressor very effective, I have a little trouble adjusting to a proper phasing. personally I find the delay a little cold but it has no particular stigma. is an analog multi-effects to get the best I think we play hard with a tube amp, it also seems to react better with double coils. it is clear that this device does not leave a stack of its low volume or with headphones like a modern amp modeling. Luis I put 7 but that does not mean much. You can not compare it to what is done now.


I have since qq months because I wanted an easy to use analog effects
He faults and qualities of products namely one boss neutral, great personality. it colors nicely sounds of a guitar plugged into an amp correct correct. If you keep the one that you do not have to buy a modeling effect that mimics the sound of the GP8
