Does anyone know of any mod to get more distortion from the pedal? The distortion is weak & I'm looking to get more out it?

Thanks

Brian Marshall

if there is anything that thing doesnt need it is more distortion.  you should play arround with frequency response via eq pre and post distortion.  Use compression, and noise gate in front of it....

How are you using it.

Modding the amp models is impossible.... you are talking about the analog distortion right?

Heavyriffing

Do you own one? Because the distortion is terrible I have to use a distortion pedal because theirs is too weak. If you can suggest some settings please do, but I've been through all the setting to no avail

I've heard the distortions in there are indeed analog. Crack it open and see if you can identify any of the distortion sections. If you can, then yes, you should be able to mod it somehow.

Brian is right; changing the COSM code is going to be just about impossible.

Use a compressor and boost the signal slightly pre-distortion. You might be able to use the EQ to boost the signal. EQ is also great for tailoring the distortion.

Will you be playing in a band setting? Usually you don't need as much distortion as you think you do when you're playing by yourself. If that's the case, try it while playing with others and see if you still need to mod it.

Yeah I play in a band but instead of the GT-3 I use a zomm 505 for distotion now & does anyone know how I can get a bit more out of it? the 505 I mean.

The Zoom 505 is 100% digital. My father has one here at home, and I don't think you'll be able to mod it, sorry :(

From my experiences with it, it gets pretty over-the-top if you want it to, but the resulting quality of the signal is very bad. It will do that heavily rectified sound, but I couldn't get a decent crunch or milder overdrive out of it. Sucks the tone out of your signal as well. The 505 has a sample and hold filter that isn't included with the boss; aside from that I think everything is much, much better on the GT3.

The GT3 has a completely switchable effects loop that you can place anywhere and doesn't "nullify" the onboard distortions (like the GT6 does), correct? There's no harm in continuing to use the 505 in that loop so you avoid the massive tone-suckage. The GT3 will then handle your equalization, normal effects and patch switching.

Since the 505 can't be modded, my advice is to look for a distortion pedal that fits your needs - if you build stompboxes, check out the amp sims at RunoffGroove.com and see if they're heavy enough. If not, the MXR Distortion+ might do what you want, otherwise you might want to buy a Boss HM-2 Heavy Metal or Metalzone pedal. I haven't used either of these but I think they get pretty heavy.

Perhaps my favorite distortion pedal is the ProCo Rat; that's another option but I don't think it gets metal sounds too well if that's what you're after. What sort of music do you play?

Once you've found one, either use it by itself or stick it in the FX Loop of the GT3 and continue to use that for your other effects. I've used a GT-5 and the series is very good, especially for the price you can get a GT3 for on ebay these days.

Hey thanks man I appreciate your help

No problem, and after re-reading my post, sorry about the Zoom 505 bashing :) You'll see lots of self-important tone snobs really bashing those, but if they work for you then they do a lot for not too much money.

Another suggestion for your existing setup is to try running the noise gate on the GT3 before the FX loop with your Zoom 505 in it. That should cut down on the amount of noise that gets amplified by the high gain presets on the 505 (like factory patch A1, if I recall correctly).

hey heavyriffing.

I owned a GT3 a few years ago, and currently own a boss GX700, which is sort of a rack version of the same thing.

First things first.  I'm not trying to be a snob, just speaking from my experience.  YOU DO NOT WANT MORE GAIN.  You want a different tone.  I can probably help you out a bit, but I need to know what the rest of your set up, and what tone you are looking for.  If you are playing through a small amp, and using a fender strat you metal tones are really hard to come by.

That said, here is the first thing i would try..... set up your effects chain like this.

noise gate>compressor>EQ>Distortion>EQ  (there should be a second EQ available from the mod section)

use the compressor and noise gaite at a factory setting that seems close.  Use the metal distortion.  Cut some bass before the distortion, and push the mids just a little.  leave the distortion eq flat, or close to flat.  dont turn the gain past 50.  on the second eq stage, boost bass, cut mids just a little, and no matter how much you want to dont boost the highs.  they will get unruly playing with the band.

That said, when you listen to a metal album those guys are usually playing with about 10% of the bass you think they are, and wayyy wayyy less gain than you think you hear.  Recording or playing live with a full band is all about keeping everything tight, and making the whole band sound like one insturment.(well sort of)
