Portable Power Amp with Explosive Tone

Small enough to find a place on your pedalboard or tuck into a gig bag, the Electro-Harmonix Howitzer 15-watt Power Amp pedal is a bona fide portable guitar rig that will blow you away with its outsized tone. The Howitzer relies on a Class D amp design for maximum output efficiency, belying its ultra-compact format. Tone shaping options abound, including a bright/normal switch and bass, mid, treble, and gain controls. Equipped with an FX loop, Howitzer also lets you insert your favorite effects between its preamp section and volume knob — a configuration guitarists at Sweetwater especially prefer for reverb and delay effects. The EHX Howitzer excels as a reliable backup for gigging musicians or as a creative tool in the studio. Grab yours today and get ready to lay down a barrage of explosive tone!

Note: This device is intended to drive a speaker cabinet and should not be placed in front of an amplifier or pedals.

Excellent Amp

I am very pleased with the Howitzer. Tone-wise, it sounds exactly like my tweed Champ - even the overdrive sounds identical but it can get way louder as it is connected to a 1x12 and has more wattage. With a Howitzer and my 1x12, one could probably gig a small venue like a bar or a cocktail party but for a stage, it'd probably need to be mic'd or at least use a bigger cab. I only play in my bedroom and it is more than loud enough for that. If planning to gig, I would think of it as having the same tone, headroom and loudness as a Princeton.

One cool feature is that since it's 24V, I am able to power it directly from my Cioks DC7 power supply mounted underneath the pedalboard.

Excellent value and practicality!

After 24 years of playing guitar I recently made the move to direct in options as my primary tone - Strymon Iridium and POD Go. I did, however want a cost-effective 'real amp' option after selling off my traditional amps. This little EH Howitzer looked to be the perfect option to drive my custom 1x12 cab. Size and build quality is great. After a quick sound sample with my strat direct in, I was very pleased with the tone and it more than enough power to drive my highly sensitivity Eminence GB128. What makes this little amp especially awesome is that I can use my POD Go output into the effects return of the Howitzer, bypassing the Howitzer's gain and EQ section, giving me access to all the POD Go's amps and effects (cabinet IR's off). After years of being a staunch tube amp guy, I am very pleased with this amp and the options it provides. I highly recommend this amp as a daily go to or just to have a pedal-sized backup amp.

Great quality, value and a potential solution for flat response amplification

After 24 years of playing I recently shifted to primarily using digital/direct in amps (Iridium and Pod GO) opposed to traditional amps. And I love it! Sold off my big amps but wanted something economically priced to power my remaining custom 1x12 cab. This amp does that with no problem, and sounds good considering solid state and price point, however that isn't how I am using it. I am using it to power a 5" full range ('flatish' response) PA speaker with the Pod GO's output into the Howitzer's effect loop return. This set-up bypasses the gain and EQ section providing a theoretically uncolored amp/speaker platform perfect for amp modelers. I am very pleased with this desktop setup and prefer it over running the Pod GO into my HiFi setup, which technically is a 'flatter' response with +/- 3db 40Hz-20kHz, however I feel the paper cone PA style speaker better reproduces those amp tones and sounds more realistic. If I were still using traditional amps for live play, this would be a no-braining to have in your bag as a back-up.
I took off a 1/2 star because I think it should have power switch. Highly recommend.

Awesome!

I love this amp. Bought it to power my 112 in my living room for some lower volume practice sessions. Cup of coffee and a early morning jam! This amp takes pedals very well and the crisp "clean" is what I love. The only half-star issue was that I could not get it to operate with my xvive wireless... I kept getting some sort of "tremolo"
by gabriel from CA on

Amazing for the price!

Just received this little amp today and after playing around with it for a few minutes, I can already tell it's great for a pedal platform. It has very good clean tones, and a little bit of nice breakup with the gain up. You could totally use the gain to play like 70s rock and roll. Gets plenty loud at room volume or if you mic up a cab, this thing would probably keep up at any live venue. Super small and compact. For $85 sale price, this thing is fantastic. But my only issue with it is there is no on/off switch. Once it's plugged in, it's always on. So that's my reason for not giving it 5 stars.
