Lately I've been getting really frustrated with my bass setup basically up to my amp. In specific I am having a lot of trouble with my effects pedals, and their seemingly erratic behavior. My issues are mostly with individual pedals, namely: EHX Little Big Muff (recently traded) Ibanez SB-7 Synth Ibanez PD-7 Phat Hed Boss OC-3 MXR Blowtorch I've never been able to get, what I would call, an ideal sound out of them, and they certainly have never sounded like they did in the store, which I didn't think too much of due to the fact that I was using a different bass in the store, etc. But, for the most part, they have been at least usable, if not fantastic. Recently, I got a PD-7 Phat Hed, which has been the bane of my existence .. I have found it absolutely impossible to coax any meaningful volume out of it, even with my bass and the level knob on the pedal cranked. It produces a hell of a lot of ugly noise and feedback, but no useful volume. This struck me as odd, and prompted me to do some trouble shooting on my setup. What I have come up with the possibility that my bass may be to blame.. it seems odd, but perhaps somebody out there can help me to confirm my suspicion that my bass's output is really low. I haven't noticed it until now, because I have always had my Zoom B2.1u as the first thing in my chain, and I think it may be adding enough heat to my signal to sufficiently power my other pedals, but not in an ideal fashion. I decided to take it out of the chain altogether and test each pedal on it's own, directly from my bass and into the amp, and here is what happened. PD-7: Surprisingly, I was able to get a more normal volume response out of it, but very little distortion, until the drive knob is almost all the way up. With the B2 before it, it becomes overwhelmingly noisy, with very little meaningful volume.. all just noise. OC-3: Because there is a Line level knob, this pedal seems to work okay, but it still sounds weak unless I have the direct level knob cranked up, and there is a noticeable drop in volume that was not as noticeable with the B2 first. MXR Blowtorch: This pedal has a ton of gain, with very little noise, even at the worst of times, but just straight from my bass, it was extremely difficult to coax any distortion out of it, even with the gain cranked and the Torch button on. When I turn the blend all the way down (i.e. All Pedal) THEN I get some distortion.. but it sounds very thin, as if the clean signal is just not coming through. Otherwise, at most normal settings, where I should be getting a lot of distortion, all I get is a lot of clean, kind of hollow sounding volume. SB-7: Completely unusable without the B2 before it. This pedal, being a synth, uses the signal from the bass to trigger whatever sound it is supposed to be making. What I get out of it is basically nothing, unless I REALLY crank on my strings, in which case I will get little blips and pops, as if it only JUST recognized that I was playing something. And this is with the sensitivity knob cranked. This, more than anything else indicated to me that there is some kind of signal issue from my bass. My bass is a 1991 Fender Jazz Bass Plus 5er, with the active Lace Sensor pickups. And before you ask, yes, I did change the battery, and it made no difference whatsoever. I know this was long.. but any help??!?!?!
