Guitar Preamp Tube combination

dart56 · 7th February 2008, 04:16 AM

I'm looking at building a guitar preamp. I'm not sure what tube combination would be appropriate to get some drive (nothing too heavy). I'd like to stick to readily availbable tubes. I was thinking I'd use the 12ax7 as the "second" stage to the preamp. What tube should I use as a first stage to overdrive this? Another 12ax7, or something different?
Any ideas would be appreciated!

Try EF86or a cascode 6DJ8, DC-connected 12AX7 CF, volume+tone, 12AX7.

Hi,

- 6EJ7 (fraction of the $ of an EF86 and sounds much the same. CLEAN tone)
- 6AU6 (relaxed, clean sound)
- 6JW8 (triode is like a 5751 in sound as a second stage and OD's niiiiiiice)
- 6AN8 (put on some sunglasses and get warm and smooth)

Cheers!

Pick you favorite amp that has the sound you like. Copy it.

Marshall 2203 or 2204 are both great preamps.

AX84 HO is another super great preamp from ax84.com
