One man's trash is another man's treasure

  1. I put this rig together just out of necessity, to have something in my living room that made a sound. It didn't expect it to sound great. Not even good. I just wanted it to make a sound loud enough for me to practice.

    This rig did however make me gasp. A Peavey PA head from the early 80's. A beaten up old Marshall cab from the same age. It shouldn't sound that great, I thought. I was wrong. With the EQ set flat and the volume turned up just a little bit it sounds big, clear and punchy with great presence across the entire range. Almost more balls than my main rig with a Ampeg 810 cab. Just the perfect sound, you know? And this rig got some serious power. That PA amp is LOUD. And the cab can take it, no problem. No rattles, no distortion. Huge amounts of bottom end. The P-bass with flats just sings through it. I could take this setup to a gig, no problem.

    The best thing about it is however that both the amp and the cab comes from an old rehearsal studio that were updating their stuff. This gear was about to get thrown away as garbage!

    So, humbling experience over. I love my new rig!

    Nice! A friend of mine back in grade school had a Peavey PA head similar to that and it was frequently enlisted for bass duty. What kind of Marshall cab is that?

    Nothing wrong with that rig. It looks cool. So does the old piano.

    Sweet!

    My band rehearses in the bonus room over my garage. I have an older Yamaha powered mixer very similar to yours. I was initially running everything into a Euphonic Audio VL-210. Then I decided to try an experiment. The "stand" for my rehearsal PA is an Epifani UL410. I decided to run one side into the EA cab and the other side into the Epifani.

    Holy crap! It sounds amazing. Vocals are clear. And my bass sounds ridiculously good. I'll try to remember to snap a pic and post it later.

    Hey, if your rig sounds glorious, rock it live and let it eat.

    The XR600 mixer uses the same power amp (PA400 module) as the bass amp of that era. Nothing wrong with it, though the input impedance of the mixer might be a bit low for a passive bass.
     
  9. It's a Marshall 1550 cab. 1x15", 250w, 8 ohm.

    Well, you know... A mancave is a mancave =)

  10. Well, I know that the power amps are the same, I have some other old Peavey amps in the past. Absolutely great stuff! I do however know nothing about impedance and other electrical stuff. I just know that it sounds great to my ears! =)

    I was about to post the same comment. A higher impedance buffer (I used 3Meg on my passive bass) will only make it sound better than it already does, IME.

    Very nice, I'd love to snag some free gear!
    Is that head as heavy as it looks? Glad you got a nice sounding rig so easily!
     
  14. That's some good looking Jank going on there :thumbsup:

    Beats spending money. Nice job.

  16. Could you dumb that down to my level? =)

    It is heavy, yes. The cab is lighter than I thought it would be.

    Passive basses (generally) perform better into loads about 1M or higher.

  18. I'm no expert but I believe they are telling you that a DI or bass preamp would help it sound better. Google "impedance mismatch"

  19. About 20 years ago I played in a blues band that used a XR600. It was solid as a rock dependable. I used a DI box and bass amp for stage volume.

  20. On the input impedance issue, if it sounds great to you, don't sweat it. What is right on paper or best practice for signal integrity isn't always right in the ears. That's part of the fun thing about music; nobody will die if you do it "wrong".

    That said, a better matched input impedance will mean more signal to the amp and better frequency response (specifically more high-end). The specific cable you use will have less effect on the system as a whole. Etc.

    Bottom line: if it sounds good, play it!
