: : hello.....I own a '67 coliseum bass and i still don`t know what its impedance is. Some say 2ohms. But i need to know it for sure.
: : Thanks..
: I believe Stef is somewhere in Scandanavia, and is an honest victim of some bad information regarding the date of his amp; that part is really irrelevant. Hey, Stef, just so you know, the Coliseum amp series was introduced sometime in 1971, and appeared in the '72 catalog(which I have). Do you have the Coliseum Bass(5 knobs) or the Coliseum 880(7 knobs--added limiter and distortion), both with the black/silver/black faceplate? In the '72 catalog it definitely states that you can run a 2-ohm load on these heads. If you have a "Coliseum" head that is all black, and has a bit of an angle at the top, ala Fender, that's one of the later ones made late '70s/early '80s, when quality control began to suffer. I'm not exactly sure, but I wouldn't put less than 4 ohms on those. Even if you have one of the original ones, exercise a bit of caution with a 2 ohm load; keep a small fan on the back of it, don't play alot of high transient stuff like slapping or popping, and don't crank the bass frequencies all the way up. Remember, this is 30 year-old transistor technology, and while these amps were over-designed for those times, getting one repaired where you are may be a problem. What kind of speaker set-up are you using? Good luck, hope this helps!
OOOOPS! Yo, Stef, sorry, I just found one of your earlier postings where you stated you were from the Netherlands(not Scandinavia!). Sorry about that! Hey, you would have loved the show I saw last week...Motorhead, Nashville Pussy, FuManchu, and Speed Dealer...ouch! Yes, I had my earplugs. Are you a fan of The Hellecopters or Queens of the Stone Age? If you're ever in the mood to check out obscure early '70s heavy rock, look for the first three albums by Cactus(there's a good "best of" on Rhino Records, if you can get stuff on that label where you are--but don't bother with their fourth album, "'Ot 'n' Sweaty"), featuring the killer bass playing of Tim Bogert(playing through Sunn amps, I believe, but I'm not sure)--this band was in between his work with Vanilla Fudge and Beck, Bogert, & Appice. Definitely Camaro-drivin', bong-loading rock-o-rama(I'll explain later, it's an American thing...).
