  • Rangemaster clone: Too much compression

    HI! I've built a Rangemaster treble booster clone cause I saw pretty cool videos of it on youtube and liked a lot. I finished it yesterday and started with the tune up process, trying different transistor (all NOS Ge PNP) and adjusting bias, with the DMM and by ear. It works good, but no matter what transistor I use, it gets some compression on the notes on the higher settings of the boost pot, and I donīt think I like it, it feels strange when playing with that compression. It's that normal for this circuit? Thanks!

    The performance/behaviour of the Rangemaster will depend partly on what it is feeding. The compression may be coming from the amp, but may be the interaction of the booster and the amp. Ironically, one of the things people like in a booster IS the additional restriction of dynamic range it can produce in some instances.

      I guess I'll try it with other amps. Maybe it's not the effect for me! The same thing happened with a fuzz face clone I made, I didn't like it, too much compression and too bassy, my guitar was burried in the mix.

        It IS used for compression, the basis of the sound for Clapton, Brian May and Ritchie Blackmore, among others.

          Yes, but the thing is in the videos I've seen it doesnīt sound like it's compressing too much, maybe is the nature of the youtube videos that mask it, or the fact that is something more to do with feeling while playing rather than sound when you listen, anaway my rangemaster seems to compress in a way that when I hit a note or chord, the inital attack sounds bassier, then it gets more treble while mantaining the same volume as the sound decays, like a wah effect. This effect is a little less prominent with less voltage at the emitter.

            Well, I discovered that the problem is not the pedal itself, it's the amp being pushed hard by the pedal! Since the boost control on the pedal is like a volume control, not a gain control, the pedal is always working the same, the boost pot just controls the output level. Lowering the gain on the amp solved this, I also tried a samller cap at the input of the pedal and this also helped.

              The rangemaster and fuzz face both react well to your guitar's volume control. Try rolling it off a bit.

                Yes Knasher, it's like you said, rolling back the volume on the guitar solved this, but the problem was in fact the interaction between the effect and the amp, was like some blocking distortion or something, anyway I did more testing and find out that this effect was not what I was looking!
