Hey Y'all,
I have a Fender Blues Deluxe Reissue, and I love to play blues, jazz, and classic-style rock. Is there any way I can get a good amount of headroom on my clean channel for a nice warm jazz tone, but still be able to get a good, thick overdrive? If so, what kinds (brand and type) of tubes can I use for this? would a power attenuator help? Thanx y'all, any help would be greatly appreciated.

Hi 6-a-phone! Well, you must have 12AX7 on your preamp, maybe you can switch them to 12BZ7, they're the same but half the plate resistance, so (after doing some maths) you'll have 3 more dB in each stage. Also, you can put these 12BZ7 and a lower gain first tube, like 12AV7, 12AT7 or even try a 12AU7, the lowest gainny of this kind (I think).

That's a pretty loud and trebly amp for harp. :(
The lower gain preamp tubes like the 12AY7 will give you more control but you won't get good breakup 'till your LOUD. :eek:
An attenuator will take care of that AND will scrub a little treble off.

Yeah, I was amazed at the headroom difference I got from tubes especially selected for headroom by the guys over at Eurotubes. I just changed out older JJ tubes for newer ones and asked for a set that would give me more headroom. I had to turn the gain WAY up after the change to get it to break. I had no idea the same kind of tube would have that much variation.

Tube Guru's--how is that possible?
