This coming from someone who's never played a dumble. So then why would i say that? Because, the concert's distortion was horrid! If a dumble's OD is remotely as good as it's said to be, there can be no comparison. The clean sound is a different story, and where the concert sounded good. The distortion was one of the worse i've owned, and i've owned a lot of amps in 40 years of playing.
Good reason the custom amp builder modified the Concert II. Maybe the Twin Reverb II
and the Concert II (as other Internet comments have mentioned) provide
a good/great "base chassis foundation" and/or initial circuit design
allowing improvement. Maybe the Concert II/TR-II are the best priced
amps that are factory produced and easy to procure.
This particular custom amp builder never declared any comparisons to Dumble,
many others have (search the Internet) and this is the reason for my post.
But, this particular amp builder states his newly highly modified Concert II
is as clean as Ted Nugent tones using a Tweed 1950s Bassman;
and as distortedly crunchy as early Eric Clapton 1960s Marshalls.
Also, he states to have created "his special version" of amp circuitry
that manages NFB electronics while controlling NFB output.
He's starting a boutique amp building business based upon his theorys.
Seems good to me.
I do agree that Factory issued Fender-II amps are not Dumble amps as shipped.
but, there must be something SOME players/amp pros like AFTER modifications
and custom upgrades are applied to 1980s Paul Rivera Fender-II amps.
Don't cha think? Again, the reason for my post is this inquiry.
"I Know Johnny" ~ I agree to some point.iknowjohnny wrote:As heavily modded as yours appears to be, even if it does sound like a dumble that says nothing about the concert. You can heavily mod most any amp thats somewhat similar (or not even) to a dumble to sound like one. Just depends on how far you wanna go. But the concert was a good fender clean amp, nothing more. The drive channel is just an unfortunate addon.
But again, MAYBE THERE ARE REASONS SOME amp techs & guitar pros
do use and do prefer Paul Rivera designed Fender-II series of amps . . . . . rather than
Fender Champs or Twins or Deluxes, solid state amps, Marshall amps,
Peavey amps, Silvertone amps, Gibson amps, etc etc.
If this possiblity exists, then the reason for my post and inquiry
