I've got an OLP Levin which plays really well, but the preamp will easily distort if I dial in too much boost. I'm presuming this isn't normal ? (Never played an active before). Can anyone recommend a cheap upgrade? (Don't want to spend a lot as it's not in keeping with the bass!!) Any ideas?
I've got one of these for my rogue lx406-pro because i used up my budget on the pickups with bartolini's so I didn't have a lot to spend on a pre. I am not sure how it sounds to some of the higher $$ preamps but it sounds worlds better that the stock rogue one. It is very clean, transparent, hi-fi sounding. For the price its not a costly mistake
You could alos check the Artec preamps http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=350145952949 I have the two band version and about to get the three band. Not the top of the line but better than some of the stocks and works well for me.
Spend some time on EBAY. I got a Bart NTMB 3 way for 90 bucks and they always have aguilars for cheap.
Are you sure it's your preamp. Are you running into a padded input on your amp. If you are running into the passive input you may be overdriving the preamp which is causing distortion. If this isn't the problem, I would second the recommendation of 3506string. I have used the 2-band version of that preamp in two budget builds, and it has impressed me in both basses.
