I get an incredibly punchy and great sounding tone out of this amp. My friend with an SVT-3 head says he wishes he would've saved his money and bought this head instead.


Drives my Eden 410 XLT and 15 like a champ. I can easily overpower any guitarist. I play thrash metal, and with this setup I have never had to turn it up past 7. Good even frequency response over the entire range. I have spent twice as much for a lot less. Made in China. I guess that is the only way they can be so cheap. I am guessing it is pretty durable. We shall see.

Great Amp

I love the sound of the amp and the power it has. I've never had to turn it up all of the way. The EQ is super simple and idiot proof which I love.

Great sounding, power head

I have to agree with others that this thing sounds great right out of the box. But it does sound different from the old Trace Elliot head I was using. I understand how the vintage style passive tone stack works (same as my Blue Tube pedal or what you find on an Alembic preamp), so with that in mind I set all the controls at about 6 to start with. From there I was able to tweak the mids and highs to get just about any tone I wanted. it's a very clear sounding amp, and took me a little bit to get used to, but I'm really enjoying it now. And it's loud. It doesn't song like the solid state Hartkes, but it does have a great warm tone, while being clear as a bell.

I'm Lovin It!

I love this amp! It's well made, sounds great, and doesn't have a ton of knobs and buttons to make things confusing. I just set the bass, mid, and treble to the neutral position and then dial up my tone on the guitar with active EQ. It's so simple it's stupid. Thank you Hartke for giving us a great sounding amp at an affordable price! It's warm and punchy and has all the power I need. If you are planning on playing a big hall then I would suggest the LH1000. But for a 2-300 person venue with a decent P.A. system the 500 is more than enough for on stage presence. HARTKE ROCKS!
