  • Padded Cover for Acoustic Array Pro Combo (and Gollihur Series)


Jeff is a fairly regular visitor to the Gollihur Music HQ, and he brought one of these fabulous amps (pre-production) for us to check out. Now, we don't normally do "non-bass" stuff, but Christopher is a gigging acoustic guitarist, as well as a bassist, so we were able to quite effectively put it through its paces. It's got truly transparent sound, with the same "width" of stage coverage as the Bass Array cabinets - in fact, with higher-frequency content, that width might even be more apparent (and effective.)

Includes our exclusive Gollihur Music tipsheet to get the most out of your purchaseDual-channel inputs provide for either multiple inputs or dual-source options (do you have a mic and a pickup? two mics? go for it!) You could even easily use this amp as a mini-PA for coffeehouse gigs; plug a guitar in one channel and a vocal mic into the other - and you're golden. Instrument inputs with a 5 megohm input impedance allow you to use a passive piezo setup (like a K&K Pure Pickup) without any need for 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 attenuation. Built-in digital reverb and chorus provide spaciousness and color to your sound.

The combo's power section delivers 150 watts to its internal speaker array -- and if you add an additional extension cabinet, you'll be pushing 300 watts. It's a formidiable, yet very compact, rig; excellent sound, really nice depth, and enough volume for almost any gig. 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 guitars or blend.

The Acoustic Array Pro has a smart design with a slight angled orientation, to get the sound "up in the air" rather than pointed at your feet - and it also has a built in post stand adapter (see photo below) for mounting up high for the most efficient sound dispersal.

    The tone is full but clear.

    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. I'm still learning how the controls interact.
