Double Bass Henriksen Amp Question

[dylanjohnson]

I'm playing a jazz guitar fest here in California and spoke to the owner of Hendrickson Amps. He's aware of the hole that the demise of Acoustic Image and Euphonic Audio has left (as well as the demise of the GK MB150) and is working on a bass amp. Probably a combo. I have high hopes. I'm going to see him today again. What do we need from this thing? HPF? Two channels?

 

[Earl]

HPF for sure. 1meg input impedance. Low mid and High mid.

 

[DoubleMIDI]

Better 4.7 to 5 MegOhms input impedance.
It is easy to lower the input impedance by a short adapter cable with a resistor in it, but to enlarge the input impedance the amp has to be modified.

The high pass filter has to be frequency adjustable from 30 to 150 or 200 Hz and (at least) 12 dB/octave.

A mute switch is helpful too.

The EQ at zero position (middle) should have a straight frequency response.
Optional switches to alter the shape of the frequency response.

Two independent input channels with full EQ, at least one of them with a phantom powerable XLR mic input too.
The input should accept high input levels without distorting and the gain range should be rather high.

Speaker output should be able to drive a 2 ohms impedance, 600 watts minimum at 2 ohms.

DI out, switchable to pre-EQ and post-EQ, switchable at mic and line level, ground lift switchable.

Optionally line in, Bluetooth audio in.

Effect loop and line out (to drive an additional powered cab).
Effect loop in parallel and with a dry/wet mix between effect and dry signal.
Maybe an internal effect (reverb, delay, flanger, chorus, phaser).

I’m sure I forgot something, but this is at least the most important.
Some things could be dropped, but most are important.

Pole mount!

Why not switchable as seen on the Felix?

 

[Chris Fitzgerald]

Wow, that would be really great news! Their guitar amps are really great. I would say piezo-friendly input impedance and a variable HPF would be the top two items on the wish list for sure.

 

[dylanjohnson]

Thanks, guys. I go back later tonight and will see him then, so keep the ideas coming!

 

[DoubleMIDI]

If it becomes a combo, a removable amp would be nice, like with some AI amps and the Genz Benz Shuttle Series.
That way it could be sold as an amp only or as a combo.
With a pole mount for the cab the knobs should be placed at the front.

 

[Martin Spure]

I agree with everything @DoubleMIDI wrote above, but would like to add a phase switch on the mic/xlr channel, as well.

EQ section with semi-parametric control for all 3(4?) bands would be very nice (like on the old Eden traveler heads or the Vintage Revolution Acoustic Box II preamp)

 

[bassfran]

External speaker jack, mute switch, hpf and piezo-friendly input.

Did you mean Henriksen?

 

[lurk]

Sure, all of the above suggestions along with a built-in tuner, several choices of color, and under 10 lbs and $600.

Ha ha. And small enough to fit in my pocket.

 

[Ben Rolston]

I think weight vs form factor is really important. The GK150mb is a great example of an amp that isn’t the lightest, but because of its shape it carries close to the body. The Genzler small combo (just for instance) sounds great but is hard to carry with a bass because of its boxier / cube style shape.

 

[massimo]

HPF, 1M piezo friendly input, parametric mids, weight:under 20lbs with a portable form, punchy that cuts in the mix, handle in the bottom to tilt it up (as the wizzy10) or small speakers on the top to better Hearn yourself playing (as on philjones flightcase bg300)

...Cappuccino machine with built in grinder.
Jeez. Youse guyz.
Srsly - How about a 10+ yr. Warranty? (In the spirit of Acoustic Image.)
Thx.

 

[dylanjohnson]

Yes! Thank you

Did you mean Henriksen?

 

[bassically_eli]

I'm addition to the variable HPF and piezo impedance level, I want a phase control. I also really like the harmonic enhancer feature that Headway offers on their preamps. It would be great to have that on a combo.

 

[Sean Riddle]

Echoing one other person, but phantom power and possibly an XLR input for a mic (or provide a converter with the amp like Acoustic Image did with the Clarus).

+1 If it's too big I won't be interested. A big part of AI's popularity and what made them unique along with the DB friendly features was the small size.
