7 Day Trial on all amplifier purchases at Gollihur Music7 Day Trial Period on Amplifiers and Speaker Cabinets

We know that it's tough to buy new gear over the Internet. So purchasers have a seven (7) day trial period during which they may return the amp in new condition -- NO QUESTIONS ASKED! -- for a full refund, minus all shipping costs and a small transaction fee to cover credit card processing. Call or email us first: returns must be preauthorized; a restocking fee applies if the unit is not returned in new condition.

Jeff Genzler is a fairly regular visitor to the Gollihur Music HQ, and he recently brought one of his fabulous new Acoustic Array Pro amps (for guitar) for us to check out.

We loved it (Christopher, also a talented guitarist, put it through its paces), and we even tried it with upright bass. It was a little bit too "shy" down low, in my opinion, due to using a more guitar-friendly woofer, but it still sounded quite good. Jeff was interested to see if it might work for double bassists, and I thought that it had potential; the features built into this amp are the kind that are on almost any bassist's wish list - high-impedance inputs, XLR (mic) inputs with phantom power, multi-band EQ, high quality DIs...

I couldn't help thinking: "Wouldn't it be great if we could use the killer head in this thing, and pair it with the guts of the Bass Array 1x10, for upright bassists?"

Jeff thought that was a pretty nifty idea, too. So we put our heads together and made it happen! This amp is the result of that partnership.

This new "Gollihur Series" Acoustic Array Pro, made specifically for bassists, has truly transparent sound, with the same "width" of stage coverage as the regular Bass Array cabinets. And that's as expected, since that's basically what it's packing under the hood - a BA10-2 Bass Array cabinet, being driven by the brains and power of Genzler's fantastic new acoustic instrument amp.

The dual-channel front end provides for either multiple instruments or dual-source options -- do you want to blend a mic and a pickup? Two mics? Go for it, dude!) One of our bass friends, self-professed "gear junkie" Rick Wolff, also suggests that using a simple A-B footswitch, you can optimize one channel's volume and tone for arco and the other channel for pizz, and switch between them with a simple foot tap.

The instrument inputs, with a 5 megohm input impedance, allow you to use a fully passive piezo pickup without any need for fiddling with any external preamps. A 3-band EQ and contour control - on each channel - allow for precise tone-shaping, and a phase switch can help with feedback troubles. For clear and tight bass response, a (fixed) High-Pass Filter is built into the amp, which is set just under 40 Hz. This filter (aka a "low-cut filter") provides better clarity in the low end, and removes some of the low frequency flutter and extended lows that can rob the amp of power.

The amp can also very convincingly amplify electric bass guitar, with a punchy sound and plenty of "in-your-face-ness" if needed; so for you doubling players out there, you can plug your upright into one channel, and your slab into the other - while there's no channel switching, there are separate volume knobs for each channel, so you can go back and forth pretty quickly with a simple knob turn (or use the volume knob on your electric bass and a docking station on your upright.) And you can still send separate feeds to the house with the assortment of DIs on the back panel.

The combo's power section delivers a hefty 150 watts to its internal speaker array, meaning - it's rated at 150w but has plenty of headroom to really make the cabinet "shout" if necessary. And if you add the additional matching extension cabinet (or another speaker of your choice), you'll be pushing 300 watts through the pair. It's a formidiable, yet very compact, combo; excellent sound, really nice depth, and enough volume for almost any gig (if it's not loud enough to carry the room, you're probably playing through the house PA already anyway). Its smart design with the "angled-up" front panel really puts the sound up where you can hear it, even if it's on the floor - and you can even pole mount this amp -- a pole mount socket is built into the bottom!

And it has clever built-in DI options - for use in large gigs where you need to send your signal to the house and use your amp for onstage monitoring. There's a master (post-EQ) DI output, as well as a pair of pre-EQ DIs (one for each channel) if you want the soundman to mix and process your source blend.

Check out what they had to say!
I received the Genzler Acoustic Array combo. I used it on one gig so far and I was impressed. Although it wasn't a particularly big room, I barely had to turn up the volume knobs. It seems like it's not just the volume but the projection. And the tone is full but clear. I'm still learning how the controls interact.
William C (December 2017)
Just want to say how happy I am with the Genzler Acoustic Array pro amp. At band all my bandmates and I are so impressed with the sound of both doubling with the electric and the upright. Also the lightweight and small size are so convenient when playing out. I call it my little cracker box. Thank you so much for the quality service and amp. Many Blessings!
