Henriksen JazzAmp 112

[Pukka-J]

Today I traded my beloved Mesa Boogie F50. It sounds wonderful, but weighs a ton and is extremely LOUD.
For the occasional pop/rock gig I'm more than happy using my Fender Mustang III, so I wasn't using it anymore.

I traded it in for a Henriksen JazzAmp 112. The old one, with fans.
I brought both my ES-175 and my Eastman AR605CE to try it out and was immediately sold! What an amazingly pristine clean sound!!! I don't miss the reverb at all (and I have a TC Hall of Fame if I feel the need).

Granted, at home I did notice the fans, but I don't notice them while playing so they aren't that loud.
What I did hear is the loud POP it does when turning it off. Is there a remedy or so for that?

Otherwise: sweet sounding amp with both my archtops. The Eastman needs the bottom end rolled off a little more than the 175. It sounds fuller with the Eastman than with the 175, but that is probably also because the Eastman itself sounds fuller
With he 175, though sounding great, it needs a little more tweaking.
It evens sounds great with my tele (with 0.11 flats)!

Also, despite the size it is still pretty light and perfectly portable!

I guess you all know what they look like, but here goes:

they're really good amps at a great price! CONGRATS!!!

Congrat's I love my 110 and first amp I've had that I pretty much run flat EQ all the time.

From my experience a power off pop is something a lot SS amps have.

[Jazz_175]

Congrats on your new amp!
I have the newer version with Reverb and Tweeter.
I didn't know about the fans in older models

[Tom Karol]

I have a 112 and a 110 and I couldn't be happier with them.
The 'pop' is normal and nothing to worry about.

[Franz 1997]

About the 'pop' - I disagree Tom, it's electricity arcing and easily fixable - that's why in later models Hendriksen eliminated it by putting a 0.01uf 1KV ceramic cap across the switch. I found it quite annoying and quite loud when I used a jazz amp.

If you email Peter Hendriksen I'm sure he'll tell you how to get a local tech to fix it, if you want to do that. Or I have a picture of how to fix it from the late Bud Hendriksen - just pm me if interested.

I bought the amp in 2011, so I guess it is one of the later models, but I get the pop when I switch it off.

OK then, Franz, I stand corrected. Actually, mine are both newer models, and the 'pop' is pretty subtle, so I guess mine already have the cap you mentioned. My ZT Club, on the other hand, did have a pronounced 'pop' when I turned it off.

Congrats Pukka.. great getting new stuff.

So.. is there much consensus on models? 110, 110ER, 112, 112ER? How do the ER models work if you want to go back and forth between an archtop and a flat top?

[Tom Karol]

I believe the ER models now have an on/off switch for the tweeter - turn it on for a flattop, off for an archtop. I had the outboard tweeter for a while with the 112. It worked well with an Acoustic/Electric Hybrid, but I found it largely superfluous with standard (i.e., magnetic pickup(s)) electrics.

I like both the 112 and the 110, but if I could only have one I'd keep the 112 - deeper clearer bass, more 3-dimensional, and fatter highs. I put a Ragin Cajun in my 110 (after playing it with the stock Beta 10A for a little while), and I'm glad I did. Being 3 db more efficient with a more prominent upper-midrange, it makes it louder and more versatile for Pop and Rock but still good for Jazz.

I generally use the 112 with my hollow-body archtop, and the 110 with my semi-hollow and my Tele. I'm still threatening to try them together (110 on top of the 112 with a dual-mono-output effects processor) as a JazzAmp Mini-Stack!

[Spook410]

Thanks Tom.. looking at these and that was helpful.

I'll wave my lighter in the air for you if you stack them..

[Jazz_175]

Hi Tom, I am tempted to buy the 110 (or that Mambo amp) to go along with my 112 ER,
however I am considering to buy the 110 JazzAmp and swap the speaker in the 112 ER, with an Eminence Legend 1258, to convert it in the 112 BLuesAmp, just the opposite of what you did.

Or maybe buying the BluesAmp 110, to have exactly your combination.
......mmmmmm.....

I'd like to have one of those BluesAmps (110 or 112) to be used with solid bodies.

Do you find that your Tele has a much different sound by comparing the 112 JA or the 110 BA?

[Bluedawg]

I picked up a 112 last fall.

At first I wasn't impressed, but I took it to some rehearsals and on some gigs and I like it now.

Maybe it needed to be played a little and broken in.

[mikeSF]

i still love my JazzAmp12. Mine was the original model with a fan but Peter swapped out the amp section with the reverb model and plugged the fan hole. no popping on this one, but originally it popped loudly every time. ES175 is a great pairing with that amp IMO.

[Tom Karol]

Do you find that your Tele has a much different sound by comparing the 112 JA or the 110 BA?

Yes, it sounds different, but it's hard to describe. The Tele with the 112 gets good jazz tone, but even with a lot of EQ and my CM Quattro it doesn't seem quite right for rock. The Ragin Cajun in the 110 has a bit more 'attitude' and works particularly well with the Quattro. I don't know what to recommend. I'm definitely keeping the Beta 12A in the 112. But it is easy to swap speakers (no soldering required), relatively inexpensive, and you can always put the old one back in if you don't enjoy the change. All that having been said, those Mambos seem quite enticing!

[Eddie Lang]

Hi. I have the JazzAmp 12 with the fan, same as the one in the OP. One way to go around the loud pop is to plug the amp into a power bar and turn the power off from the power bar.

[Woody Sound]

I believe the ER models now have an on/off switch for the tweeter - turn it on for a flattop, off for an archtop.

Ah, not necessarily - I love the tweeter on when comping ala FreddyGreen style.

That's cool, but I sold my outboard 'Tweetey' after I sold my A/E hybrid. Since you can switch it off and it only adds a pound or two, it certainly doesn't hurt to have the internal version.

My remark wasn't about the *ability* to turn it on or off, rather that you *don't* necessarily turn it off for an archtop guitar.

[Tom Karol]

No argument.

[Jazz_175]

When I use the amp with jazz guitars (99.9 % of the time) the tweeter's switch is always off.

[Tom Karol]

Looking at this exchange later in the day, "No argument," isn't quite working for me:

Woody, I did and still do understand your original remark. My response to that original remark indicated that you can turn the tweeter off if you choose to do so, not that you have to. You choose to leave it on with your archtop - at least some of the time; I chose to leave it off with my archtop - at least most of the time. There's no point of disagreement, here, just a difference in personal preference.

[Woody Sound]

Exactly, thanks.

Hi,

Just been browsing to see if I could eliminate the 'pop' when switching off my Hendriksen.

It would be good to see you picture of how to fix it.

Regards,

Eric

Just turn down the volume before turning it off...you'll be good!
