Brendan - Awhile back, you mentioned you were getting a Digitech RP100. Did you, and are you using it for bass? I'm looking for a headphone amp with a few effects, and have been underwhelmed so far by my bass Pandora (too small and fiddly, and I don't like the controls - I wish it had a pedal jack). I plan on using the thing on 'phones in my living room 90% of the time, for travel on 'phones about 5% of the time, and as a pedal into an amp for playing with friends only about 5% of the time. I may just pick up one of those damn "bass in a box" things and be done with it. I usually use my Pandora "dry" or with minimal effects. My (newbie to effects) concern is how well are bass freqs handled by the current generation of guitar processors? I downloaded the manual for the RP100, but there's no mention of freq range. There's conflicting advice about using guitar effects for bass here in the archive - it seems to be a unit-by-unit thing. There was some comment that the newer digital devices may work better, because they might have a wider passband. I also see that Korg has the AX1B, but I was not impressed by the physical quality of one that I saw. I don't think the case would live long with my size 13s and 300+ pounds. Also, it's kinda big for business travel. Am I being too picky? I have a thirty day return privilege on the Pandora, and just 'aint happy with it. My budget is under $200. More than one person has told me that a guitar effects unit should work fine for what I'm doing, but more than one person has said it will sound like crap. Suggestions and comments are welcome!
