FDP Forum / Amp Mods, Repairs, and Projects / Interesting speaker swap in a BFDR clone


What It Was!

Picked up a used Marsh Deluxe Reverb clone - PTP, upgraded transformers, Weber AlNico Classic.. airy & nice. Got it for a good price too, about what a used re-ish would go for. Problem is at gig volume it was scrawny sounding. Tried all kinds of tube swaps, NOS preamp tubes, different power tubes, not much improvement.

Pulled the Weber and stuck a Jensen C12K in there. Ka-POW! Fat, Fendery blackface goodness. Sure glad I didn’t give up. AlNicos have usually been too expensive for my budget, but for what I like in a smallish amp ceramic seems to deliver best.

I have a similar amp that I built. It have Vibrolux transformers and runs 6L6 power tubes. It was built as a stage amp. I tried many speakers in it with alnicos sounding the worst.

I settled on an Eminence Cannabis Rex. I love it. It sounds like an EV-SRO or EVM at 1/3 the weight.

There is something about a single alnico that doesn't work for me. Pair them up as in my tweed Twin and they sound great.

Oh man, I had a drip edge SFDR with an EV-SRO coffee can speaker, it was the best.

Anyway, I liked a Weber AlNico in a Classic 30, but it just didn't jibe with the Deluxe for me. Might like a ceramic Blue Dog, but I'm not gonna mess with it - the Jensen is perfecto for my ears.

Dolemite, do you still using your C12K?

I can't make my mind between this or the C12N. I have a Blues Deluxe clone with a chinese Eminence speaker, not a bad sound at all, but my strat has vintage noiseless pups, so sometimes i think it get's too bright. I'm looking for a speaker to kinda tame that highs and to play SRV and Hendrix with that full clean sound without losing the good quality when engaging a drive pedal. For me, since I live in Brazil, the best brands to find are Eminence and Jensen. I'm in the Jensen kinda feel because of their beautiful cleans, used in many fender amps.
What can you say?



Why do I keep fixing things that work?

I really like the EMI. Texas Heat, when wanting to keep the Fender vibe and getting fuller tones. I use it in my Hot Rod Deluxe and it gives you all the tone you expect from your amp and doesn't flub out at volume!
That would be my choice, outside of using a C.Rex speaker to take any brightness without modifying your amp.

Mine is pretty sparkly, but DRs sound that way.

It's a 6V6 thang.

My experience with my DR based amp with an (alnico) EV SRO is the polar opposite of 'scrawny at high levels' or excessive brightness.
However, Weber usually suggest ceramic speakers for BF type amps, and indeed their recommendation of a 12F150 also sounded great in mine, rather better than a 12A150.
I reckon that a Celestion Alnico Cream would sound pretty good too, though yet to try one.

I like EMs Texas Heats. Excellent smoky/woody American voiced speaker. One of my all time favourites!!

And I like Sica/Jensen RI C12Ks & the C12Ns.

I have some well broken in SICA/Jensen RI C12Ns in a 75 Twin that scratch that American vintage itch big time. The more they get broken in the better they sound. Also the more you push mids through a RI C12N the more smooth it plays.

Other C12N clones For me lack that vintage vibe/tonality that I remember. With my ears... Somehow Sica/Jensen captured it.

Sometimes I like a Ceramic over an Alnico.. sometimes its the other way around. Yep totally dependent on the amp

The TH is my #1 all-around choice. At one point I even loaded a 4x12 with them.

I have a Goodsell Black Dog 50, it's PT to Pt Cathode biased el34s, Beautiful amp. It's like Marshall Plexi but very American in nature. The Clean is like a Fender Super, Overdrive is very classic rock to early metal It's kinda a cross between a JCM800 and a Mesa Single Rectifier.

I like to use it to play like Brad Paisley (how he use Z-Wreck amps.. i.e. Trainwrecks) this amp doesn't it with no problems.

After demoing I'd say, 10 speakers, The TH won the day.. in those 10 speakers were some heavy hitters.

Sensitive, Articulate, Nice breakup at the right time, Smoky/woody vibe that gives a great ambience to what you are playing.

Put them in a 2x12 open back cab

"It's a 6V6 thang."

The 6V6 is my favorite power tube. I've found the best way to play 'em is to crank the amp up to 8 or 9 and use the guitar's volume and tone controls.

This works really well with TRs, DRs, PRs, Champs, and the 6V6 amps I've built. Super juicy tone, and allows control of dirt too.
