Preamp tubes


Saint Frank

Recommended Posts

Hey Miles, being new to tube-dom, I have a coupla questions (well, more like 20,000 but most will have to wait).

I just got a Peavey Rockmaster. Pretty nice unit, especially once I get a power amp that I can have some master control over (I'm using the power amp out of my Laney and have no master volume). Anywho, I want to replace the stock Peavey 12AX7s and am looking to get a more Vox-ish sound on the clean and crunch, and a Marshall-y/ Laney sound out of the Ultra channel. My understanding of the gain stages is that they are cascading with the first tube being used by all, then adding tubes up to four in the Ultra channel. I'm thinking ECC83s in the first two sockets, a 12AX7 in the third and a 7025 or another 12AX7 in the last. Thoughts?

I have been getting a lot of mail or questions in the Harmony Central forums. I have an obligation for Guitar Player Magazine, and their forum first, and its been getting a little hard to keep everything organized, so if you don't mind, can you just cut and paste your question in this forum or from your email over at www.musicplayer.com in the guitar area.

 

This way, it also helps others benefit from what you may have asked, and it forms something of a FAQ list.
