  • Boss GL-100

    Hey guys I scored a boss GL-100 off of ebay. I like the boss distortions, couldnt score the OD-20..iin fact got screwed on one by a sniper at 4seconds.

    I got it for 45$. Figured it couldnt be that bad, especially after reading reviews on here .

    So it came today. I hook it up to my carvin Xamp, via FX loop.

    at first, yuck. Not liking what i hear.

    Turn the Speaker sim switch on, turn on my amps OD channel. Hit distortion on the Boss, and WOW.

    Im VERY pleased with this thing! Its QUIET in the means of noise/bypass..

    But im curious, ive read that you can get pretty much any boss OD/Distortion pedal out of it

    Does anyone know settings for it to mimic a specific pedal? or just have a kickass setting? Im finding my own but i dont mind hearing others sounds.

    Thanks in advance!

    The GL100 isn't bad at all. It's about as expensive as a DS-1 but with loads more options.

    I have the manual if you want. Did you gewt the rack ears too (I'm looking for them :P)

      I got rack ears with it yes, they seem pretty easy to make if your good with metal. Id offer em if i wasnt rackmounting it. I can scan/photo close ups of em if you like.

      However im missing the footswitch. Im thinking i could just make one no? I figure ill wait to see what other rackmount gear i get. I have the behringer midi controller, itd be nice to convert everything to work off of that

        How is the speaker simulation feature on this preamp?

          What is the GL-100?

          It's not on the Boss website.

          EDIT: nevermind I found it

            I went ahead and picked up a GL-100 locally. It had been sitting in a shop in Brunswick, ME for over a year ... so the dealer was a motivated seller.

            I only bought this unit for its Roland-JC-style clean sounds, so the br3wt4l and soulful distortion/OD modes were a pleasant surprise. I was able to dial in some uber-saturated metal rhythm tones with "Dist I" and even copped a bit of a Dumble feel with "Drive II". The onboard speaker simulator doesn't smooth out the heavier distortions enough to make them musical in a traditional sense, so an external speaker simulator can come in handy in certain direct recording scenarios.

            My GL-100 won't be replacing my Peavey Rock Master anytime soon, but definitely fills a tonal niche that my other preamp can't. When I devise a way to create an A/B setup using both preamps, I may finally have all the basic clean and dirty sounds that I will ever need.

              Are there any other GL-100 owners on this board?

              I tinkered with the "sharp" mode of channel 2 a bit today and was able to get convincing piezo/acoustic-type tones with a neck humbucker. Aside from being able to cop tones reminiscent of a DS-1, SD-1, MT-2, HM-2, BD-2, Big Muff, and BeeBaa, the GL-100 can also mimic the AC-2 ... and it has 100% analog circuitry. These things are a steal for their current price.

                I have one somewhere... It needs some cleaning of the pots, kinda beat up but still works fine. It uses a latching footswitch for channel selection, to whoever asked. I kinda like it, especially for the price.

                I really need the rack ears o.0 I'd be interested if you could scan them in or give good measurements (in mm with a good ruler or calipers). If not, no big deal I guess. It's annoying that the ears have that little "squiggle" in them instead of just being a right-angle piece.

                I need to start using mine again--when I first got it I really liked some of the sounds, but found it hard to work into my setup.

                  The GL-100 strikes me more as the type of device around which you build a rig vs. something that would be added to an existing one. Though it can function like a pedal in most respects, I tend to think of it as a 9-channel preamp.

                    That's true. Maybe I'll use it as my "non-tube" rig-- use that as the preamp with my V-amp pro for effects into my fender FM212.

                      I have one of these Boss GL-100s, and I like the tones I can get from it. However, it's EXTREMELY level sensitive, and it gets a crackly distortion on top of whatever else it's doing, and the level without the crackle is too low. Does anyone know what this might be?

                    Hey guts I'm only 8 year late to the conversation lol, but I just got my hands on one of these and I love it. Puts the recently acquired HM2 pedal to shame mostly because the pedal is noisy while this thing is remarkably "tight" in terms of not generating any noise beyond what is going through it..

                    but I wanted to mention a quick tip to the Rack Ears inquiry. Mine came without ears and I did some online shopping and found this set of ears http://www.katerno.com/detail/s/561476/p/ATN1007/ for sale. came to around $17 with shipping.. now bear in mind though you'll need a file or dremel tool to adjust the holes just a smidge, but well worth the effort.

                    There might be others that were a better fit but going from images on the internet this was the closest sure thing i could find at a reasonable price.

                      I've owned one for about 22 years. I've used it on more recordings then I can count. I did use it for awhile in my live rig, but it does better driving a power amp then running it into a guitar amp, but its still not bad that way. It does have channel switching but not bypass mode. If you want to use it in place of a pedal using an effect loop switch so you can bypass it completely may be an option.

                      It does sound good for recording. Its got speaker emulation that removes the harshness you normally get from a preamp signal when you record direct. Its also got High and low impedance outputs, a buffered out (for a tuner or another amp) and a stereo effects loop.

                      If you plug a stereo effects unit like a Alesis Midiverb or Lexicon in there you'll hear some amazing sounds happen when you dial up reverbs and echoes. Even stereo chorus takes on a whole new sound. You can plug in mono too if you're going to use a single amp, but it really opens up when you're running stereo.

                      The preamp gain will go from super dry and scooped Strat tones on the one channel to gradually stepped up gains on the other channel. If you have a basic amp with no channel switching this unit can provide that. You can get some Boston type driven guitar if you use the high gain settings and play with the mids but overall its drive tones are a bit 80ish. Since its got an effects loop you can run other gain boxes in the loop and get more variety. I used it with a Yamaha GEP 50 (a rack unit nearly identical to the SPX90) in the loop for a long time because it had great reverbs, echo and chorus. I also ran other gain pedals in the loop for more variety.

                      Recording direct it gets you decent meat and potato tones for tracking. I haven't used mine for a couple of years, mainly because I got bored with the sounds and wanted to use something else for awhile. I've been using other rack units like an ART SGX 2000 and other modern multi effects units lately for recording but I'll likely break the boss out again at some point.

                      Here's one tune I did using that Boss recording the guitars direct. I had an Alesis midiverb in the effects loop https://dl.dropboxusercontent.com/u/...BMaster%5D.wav

                          Looks like they are touring mostly in Europe. They have one show in Arizona in November which is about 1170 miles away.

                          I'm really not into Metal much. There has to be something unique there to catch my ear and remember who did it. I may know some of their songs from having heard them on the radio but I honestly couldn't list one of their songs off the top of my head.
