I hear all this talk of how the black face amps were so great..and I have this single 12 Concert with an OD channel that IMHO is worse than when my Hot Rod Deluxe was stock. The reverb is tremendous. The clean channel is nice but I think my Chorus m-80 has a better clean tone.
Can this PTP Concert be changed?...I like the idea of having 60 watts so I guess I am asking is (can it be done without removing everything)is it worth changing to a black face circuit and still keep th 60 wtts? I have a friend who is an electronic wiz and who could do it .

Why fook with it at all?

By your own words, the clean channel blows and the drive channel sucks.

Why not sell it or trade it for whatever really floats your boat?

the clean doesnt blow..its good..just the chorus has more everything.. shouldnt a tube amp sound more dynamic than a solid state? thats why I was thinking modding to get a great tone out of it..if it doesnt mean replacing everything by putting in a 22 watt deluxe amp in a Concert Cab....and i cant afford a $1500 DR or similar vintage amp

Used DRRI's on the secondary market are now in the six-hundred dollar range.

Jcart, I'm inclined to agree with Arjay, on selling the Concert and getting an amp that would be more to your liking. It is a stock Concert II( I assume) and has that $value. If you choose to modify it, that $value changes. Having said that, modding or tweaking an amp to suit your ears is fine(it's your amp). The place I'd start is to compare the schem between your amp and ones that might be up the right alley. I'd concentrate on the pre amp section. the tone stack is a good place to start. That parallel V1 input is a very influential part of this amp's signature, IMO. Art

As Arjay said, why mess around with it. You are heading into uncharted water trying to make a Concert II into something else. I'm not aware of any mods to that amp to a "blackface" spec. You could end up with it sounding different but still not what you want. Save some time and aggrivation and put it on Craig's List. Then buy what you want.

my amp is a 1983...does that make it a concert 11? my hope was that on this site there are some that know enough about the point to point amps that would ideally say...build this section from this amp and mount it at this point in your amp...and it will have more this and that....plus if you want more this...change your amp here to this...

And the reality is, there are those on this site that know enough about the point to point amps to tell you frankly that you are stepping on your own dick in a nebulous attempt to transform your apple into a tangerine.

Period, end of story, nothing follows.

There are no "re-issue" Showmans to my knowledge.

Mine dates to a time when Lyndon Baines Johnson occupied the White House. The head left Fullerton in 1967 and the cab is from 1965. Both have been cosmetically restored and fully serviced for reliability and safety.

If you need clean/loud try a Twin Reverb re-issue. For a skosh less "loud" grab a Deluxe Reverb RI. I have both and they're terrific amps.

Blackfacing a 1983 Concert is not easy to do because that circuit is not even close to a Blackface circuit. You might just as well gut the amp and start from scratch. This amp was meant to compete with the early Mesa amps by giving you a cascading hi-gain channel.

There are mods to take that even further and give you a really great sounding hi-gain amp. That's what I did with both of my '82/'83 Concerts and I really like the results. Check out my videos...

I'm plugged straight into the amp...

I will forever fail to understand this "fear" of PCB's in amps. It's just another method of laying out the leads for the circuit. If the components being installed on the PCB are of quality, there is no difference in tone between a PCB and PTP amp.

And by your own admission, you hate the tone of your PTP amp, so why not get a PCB amp if it gives you the sound you want?

I've got a PTP wired 1980 Fender 75 and a Super Reverb Reissue. Know what? The 75 is pretty good, but that SRRI still kicks it's butt. What the heck do I care what's inside if it works, it's reliable, and it sounds good.
