    ?

    or, maybe just the preamp, and keep the BF power setup?


    kinda unimpressed with my SF twin, that has been BF'd


    don't want to sell it & buy a real tweed twin...$$


    I think the BF circuit is a bit too bright & clean for me though


    ...was also thinking of trying a pair of KT66's instead of the 4 6L6. any thoughts on this?

    thx

    Rewiring it for tweed is a major undertaking, and probably a lot harder than building a tweed twin kit. You could probably sell that for $700+ and buy most of a Mojo or Mission LPTT kit, with a pretty straight forward build. I'm not a great believer in turning a silk purse into a sow's ear. Or, how about spending the money you'd spend modding on buying a really good overdrive/preamp pedal to get the sounds you want out of it (BF Twins are great as palettes upon which to paint other OD colors)?

    hmmm, that's good advice


    I forgot about footpedals....thing is, the clean sound isn't nearly as good as my jtm100, believe it or not.


    ...I don't *really* want to hack it up; but I've had it for so long ( it was my 1st real amp ) I don't want to let it go.


    was looking around the 'net & doing some reading here:

    looks pretty interesting....a lot of it is way over my head though!

    You know, I forgot that someone used to build a unit called a "Fender Mender" that essentially cascades the first channel into the second. It's footswitchable so you keep the second channel clean, but click it the other way and you've got quite a bit of gain (although it is a peculiar kind of Deluxe Reverb II, Rivera gain). They usually sell used for less than $100 and don't require any mods...

    I actually bought this unit (made by Bill Hicks I think) for my Fender Twin Reverb. It does what it says, but I thought most, if not all, of the tones were very harsh, gritty, and pretty unusable. I opted to just use dirt pedals to get the OD tones I needed.

    The easiest wya to get tweed tone out of that style amp would be to install a Allen style raw control. 1 50k to 1m pot and some wire...

    Not Bill Hicks but David Hicks.

    Did you mess with the Negative feed back? that can really bring an amp, to life.

    I've never done it or played one myself, but I know I've heard of guys converting the normal channel to tweed preamp values.


    wait......this is a 5 year old thread??? that's awesome
