Members mikelitzguitar Posted February 10, 2010 Members Share Posted February 10, 2010 I bought a Peavey vypyr 75 watt combo amp about a month ago. I like it a lot but the speaker isn't that great and I wanted to play on a 4x12 cab or something. So I added a 1/4" jack to the back of the amp, that allows the amp to act as a head for a cab when a cab is plugged in. When a cab is not plugged in, the sound comes through the combo speaker like normal. It's pretty cool and works great! Also recently, my Line 6 Spider III died on me (which lead me to buy a vypyr in the first place). Today I decided to take the fried amp head out of the spider combo amp, and re-wire the speakers to a 1/4" input jack that allows the combo to become an open backed 1x12 cab. It has a Celestion speaker in it (lower end of course) that has much better tones for playing distorted in my opinion than the blue marvel speaker in the peavey. I was kind of wondering if I should leave the spider iii "cab" open in the back and in a small section of the front where the head sat, or If it would improve the tone or be beneficial to close both of the sections with plywood?

Members mrbrown49 Posted February 10, 2010 Members Share Posted February 10, 2010 I'd leave the back open. I generally prefer open back cabs anyway. The front hole? Not sure. I'd leave that open too unless it sounded off. Link to comment Share on other sites More sharing options...

Members Belva Posted February 10, 2010 Members Share Posted February 10, 2010 Is your vypyr a 112? If so, why not just put your Line 6 speaker in the vypyr cab and be done with it? I do like the sound of the Celestion speakers in the Line 6 amps. I have one paired with a Jensen Mod 10 50 in an open backed cab. Laugh if you wish. It's a match that works well!

Members mikelitzguitar Posted February 10, 2010 Author Members Share Posted February 10, 2010 Well the cleans seem to sound better on the peavey, and the gains sound better through the celestion. I wired the peavey that way so eventually I can play it through a 412. The way I did it It either plays through the combo speaker or the cab speaker... is there a way to set it up so that when a cab is plugged in it plays through both the combo speaker and the cab speaker?

Members Belva Posted February 11, 2010 Members Share Posted February 11, 2010 I believe the Vypyr is a tube amp? You will run into impedance mismatch problems if you set it up that way. Solid state amps pose less of a problem if you run, say 8 ohms with one speaker and 4 ohms when plugged into 2 parallel 8 ohm cabs. If you have an output transformer that can be switched between different loads your golden. I don't know anything about these Vypyrs. Link to comment Share on other sites More sharing options...
