    I'm looking to start building up my new bass rig. I was thinking about buying a basic pre amp (any suggestions) and using a PA power amp (possibly adding another in the future as i add more cabs). Are there any problems with this idea.

    This is done all the time.

    Check out Crown, Crest, QSC, Stewart. I am sure others will have more suggestions.

    As a newbie here, it was suggested to me to use my exisiting Mackie 1400 amp I used for my bands PA and throw a preamp on top of that. It gives me plenty of options and power but as a hobbyist, it may be overkill for my needs. I was thinking of going with a Mesa Walkabout and a 2X10 for starters. If your interested, I might let my Mackie 1400 go. You can PM or email me.

    Hi, I run my preamp into a Mackie 1400i. It probably is too much power for a hobbyist, but headroom is always cool. You could run only one side (stereo mode, not bridged) and do just fine. How many watts is your cab? One side into 8 ohms is only 250 watts, or 425 into 4 ohms.

    I think the 1400i is a very good amp. It's got a lot of protection circuits (4 I think!) to keep me from frying it, 1400 watts into 4 ohms bridged :D , and a thru XLR out to run DI to the board.

    I'm still trying to sell my guitar gear so the only thing I have that'll be used for the bass rig is my Shure Wireless system, Furman SPL-8, and the Mackie. Any idea on a moderately priced preamp for rock, classic rock but is flexible enough to do a little of everything? What about the Eden 100 Navigator? I've seen them used for about $500.

    I picked up a used Sansamp PSA-1 off ebay for around 300. It goes for 600 new. It has midi channels so you can create different sounds, save them and call them up when needed. (rock, reggie/dub, distorted). It has a load of presets too.
    I'm running that into a QSC PLX.

    at the moment all i have is a Peavey TNT combo, but my band is starting to play larger gigs (and i have to compete with two guitarists with mesa dual recs) and i need a better rig, so i'm starting from scratch

    any suggestions on what pre, power amp and cabs would be great. I was thinking or either a 4x10 or 2x10 with a 1x15

    Carvin gives the most power per dollar. I've heard about problems with service that I can't substantiate.

    I have an Ampeg SVP-Pro pre amp. Good pice ($450 US) and does everything you could ask from a pre.

    I use a QSC-RMX2450 amp.
    Stereo, per channel:
    Bridged Mono:

    These go for about $650ish.

    I Use BagEnd cabs.
    S15B-D, 8ohm,200-400watt 115
    D10B-D, 4ohm,400-800watt 210

    These were $500 & $600.

    I hope that helps.

    The PSA-1 has 10 bass presets and the rest are dedicated to guitar. I think that it has about 40+ user presets that you save your on settings in.

    Hmm, all the reviews I've read thusfar describe the tone I like..the "Moving Pictures" tone. I think I'll look into that.

    I paid for all my gear myself. Well, me and MasterCard.
    I have a QSC RMX 1850HD in my rig. Great sound, plenty of power, 2 ohm stable, and CHEAP! If only it were lighter and the fan a little quieter, it would be perfect.

    Lord Valve sells the QSC RMX amps cheaper than the equivalent Carvin DCMs, but you have to call or email him for the price.

    A poweramp is a poweramp, unless it's a guitar poweramp in which case it is crap. :D
