The Shape EQ is a good example of a flat frequency active eq pedal with a fendery treble control... So it's doable. I think a barbeq with a nice reverb into a class d power amp would be an amazing jazz amp, someone should do it.
PS - The RC Booster and the Jazzmaster Ultralight both have a 10k center frequency but as you add / cut gain the center frequency ends up reaching regular treble frequencies for guitar... I actually find the treble control on the RC Booster extremely well designed for electric guitar. So it's not just a matter of center frequency but also how it works.

but the barbeq which has a center freq of around 4k-5k works much better. 10k is just too high and IMO, the amp manufacturers who make this for guitar are just too lazy to design a specific preamp for guitar. Most of them just use a standard bass freq preamp design.

Do you have the 8", 10", or 12" Quilter? How do you like yours for gigging using acoustic and electrics? Thanks for any information.

I took the plunge and got a Fishman Loudbox Artist yesterday after trying it out with my acoustic archtop. I was quite impressed with how it provided a clean, balanced sound, as well as plenty of volume. And at home at least no problems with annoying piezo squeak or feedback.
I was actually surprised when I plugged in my Epiphone Joe Pass and got a beautiful mellow jazz tone--in fact even nicer than what I get with my Fender SCXD. I thought I wanted "tube warmth", but I guess what I needed was a clean circuit with responsive controls to fine-tune that warm yet bouncy sound. Though there's a control for cutting the tweeter response, I found that didn't affect the magnetic pickup sound too much, though it did mellow out the piezo sound with the acoustic.
An extra bonus is the auxiliary input which is perfect for feeding in iRealbook tracks from my iPad for practice.
i am looking forward to taking this with me to a gig this week with my 2 guitars. The versatility, loudness (200W) and small size should make this a great gigging amp.

fishman loudbox is a great amp. Anyone who plugs their acoustic into a full range system will be blown away if all they've ever heard it through is a standard guitar amp. That's one reason I love the AI corus. Sounds amazing with my taylor.

I gig with the 8". For recording I sometimes also use the 8 with an extension cab with an Emminence Big Ben (15"). Gives it just a slightly bigger sound. Originally Posted by marcar

no single speaker solution is going to capture the sparkle of an acoustic guitar properly. You need a full range system for that.

Update: I took the Loudbox Artist to a combo gig last night at a small restaurant--acoustic piano, amplified upright bass, me, mic'd singer. The first set I played my Harmony Brilliant Cutaway--acoustic, with a Barcus Berry contact pickup run through a Fishman Pro Eq 2, the second set I used my Epiphone Joe Pass with no preamp.
I kept the gain on both at about 12 o'clock, turned down the treble on the acoustic, put the tweeter control at 12 o'clock and added a bit of reverb. I also cut back on the treble and brilliance on the Fishman preamp on the acoustic. For the Epi later in the set I added a bit of slap echo as well, which really brought out the notes on soloes.
Verdict: really pleased with the sound. The acoustic sound takes a bit of fiddling--low and high tones sounded perfect, middle just a little brassy for want of a better word. It could have as much to do with bronze strings and pick as the amp. But the volume was fine with plenty of room to turn up if I needed and no annoying piezo quack. I dialed the sweepable antifeedback dial to eliminate feedback and tone buildup and got a really nice clear acoustic tone.
The surprise was the electric. Our bassist said he had never heard the guitar sound that good--mellow yet with enough brightness to make the notes stand out. An improvement over the Fender SCXD, which I had thought was a great amp for that guitar. And really loud if I wanted it to be without any distortion. Also certain frequencies that had a tendency toward tone buildup and feedback with the Fender were normal and balanced with the other notes.
All in all a great evening!

Dr. J, I can see your knobs are set almost like mine! I'm with you, the first time I plugged my L-5C with floating JS into the Fishman I was really surprised. It opened my eyes to the value of full range systems and appropriate EQ. My band mates like it too and have complimented my sound when used with my Sadowsky JH, my L-5, and my full acoustic Trenier.
One day I'll probably upgrade to an Acoustic Image, but until then my Fishman is my poor man's Coda.
-
I'm in the same boat L5C and the Loudbox really work well together. TBH, I was never happy playing the L5C with my otter amps but the Originally Posted by kamlapati

I have to say my Sadowsky JH sounds most optimal as an electric guitar with my Henriksen. But the Loudbox makes it sound more like an acoustic Archie .
Looks like we have at least 2 of the same guitars.

Sort of an older thread here, but... Originally Posted by Petimar

if he's got the 8" version, the freq response of the 8 is a little wider. I'd be interested in the tone stack on the micropro because on the aviator, it was too thick in the mids for a clear jazz tone, IMO. I think with a few tweaks, quilter could be the best jazz amp on the market but the preamp needs a bit of work.
-
no love for the Tech 21 Trademark 60? i still think that is a very capable and lightweight SS amp. i have used it for/with my electrics and classical/nylon string guitars. it sounds great. it sounds especially good once that stock speaker is swapped with an Eminence Cannabis Rex!
over.

Hmm, here's a video. Originally Posted by jzucker

Sometimes the cost effective solution is a piezo tweeter, so a mid-bass woofer (cheaper, easier to source) can be used. Alternately, a real diaphragm horn is used, for the sake of increased projection ... not a concern in a small venue. Neither is necessarily required for the high end of a guitar ... even the crispy overtones are lower than sparkly cymbals. Interestingly, Chet Atkins' favorite amp for his solid-body nylon string was a MusicMan 112RD50. Makes sense, my RD50 had a stock speaker with a huge top end response ... I changed it out right away, much too hi-fi sounding for my purposes. Originally Posted by Woody Sound

I wouldn't buy into generalizations, especially about modern transistor amps and the speakers they are commonly paired with. Try different amps with the guitar in question ... the only way to really know for sure.

ugh...sounds horrible. Sorry... Originally Posted by Woody Sound

But, here's a common high end vintage speaker ... I've had several of them, a JBL D130. If you look at the linked jpeg, you'll see the original spec sheet for that JBL speaker, and under frequency response, you'll see it goes up to 17,000 cycles/ second, courtesy of the integral aluminum cap. There are all sorts of full range speakers used in musical instrument amplifiers, not just a "standard" guitar speaker. Enjoy. Originally Posted by jzucker

no, a jbl d130 does not go to 17k at anything near it's linear efficiency. It likely tails off quickly at 100db sensitivity down to the point where it's inaudible starting around 5k or 6k.
if you've ever played a nylon string or acoustic guitar through a standard guitar cab and then played the same amp through a full range cab and didn't notice the difference in clarity and high end response, i'm not sure what to say...
On the other hand, maybe the entire industry of acoustic guitar amps, bass amps, full range cabs and so forth are entirely misguided and you alone are correct.
-
So, the JBL factory spec sheet is wrong? Wow, better let Lansing Heritage know that, man. They are all up in our faces with erroneous info. Also, where am I saying standard guitar cab?

I would but they've been out of business for years. Without a graph showing db on the vertical axis it's a useless marketing brochure. Originally Posted by SuperFour00

i'm not hearing any upper harmonic content out of that. Originally Posted by Woody Sound

Anyway, I'm outta here. As usual the trolls rule the roost.

You oughtn't to call people trolls when they disagree with you, (or endure your arrogant dismissal of relevant cites.) BTW, a "clone" ? Find the scope graph of a D130 and you'll have a cite. Originally Posted by jzucker
