My Genz benz guitar amp sometime wont turn on or give any sound unless I hit / play the strings hard. The lights come on but the amp wont make any sound until I lightly hit the top of the amp or hit the strings of my instrument hard. I have 2 of these nice amps and both do the same thing. I snt one of the to Genz Benz 8 months ago and thy said they couldn't find any thing wrong. I bought another being afraid of that one amp messing up again / as I really like them. Now I have 2 amps doing the same thing. The 1 st one that I sent off finally made a load buzzing sound when it died. Then I sent it off to Genz Benz. Now they have been bought out by Fender and the c
Could be a guitar cable, but you said it comes good when you tap the amp?
Some of these are tube amps so id take a peak and see if you have a blown valve.
They will either not light up or will have a blue purle glow about them
Check your cables - I've had similar problems with various amps playing various guitars; the guitar electronics and the amp electronics are fine, but the cable is damaged internally and this causes the same problems as you have described. Have you tried using a different cable? Buy a different one, try it out, and see if you have the same problem. If you have a friend who plays, let them plug their cable and guitar in the amp - if it works, your faulty cable is the issue. Hope that helps!

Make sure amp sound is not hitting front of guitar straight on. Get a 2nd pair of hands and while you do a test strum have the other person use hand or hands and apply pressure to various places on the body(such as the bridge, headstock, sides, etc and see if any of those affect the sound. Very light strings are sometimes a problem.
Sounds like the power amp section of the circuitry has a fault.Not easy to fix unless you are familiar with electronic circuitry.Take it to a repairer and ask for an estimate.It may be cheaper to buy another(new) amp.
Dean Vendetta is a company that makes a wide range of electric guitars. These guitars are used by famous musicians and bands such as Alice in Chains and Megadeath. If you own a Dean Vendetta guitar, you will need to change the strings periodically in order to keep your guitar sounding bright and crisp. Without changing the strings, your instrument will sound dull due to dirt and oil build-up on the strings.
I would try hitting the side of the amp before turning it on. There may be a loose piece of solder or other conductive particle stuck somewhere. Bang the cabinet rather hard with your fist. If that doesn't help it might be a loose solder connection at a resistor or capacitor but a tech should check that out.
If you used the speakers with another amp and they still make noise when you play certain frequencies, then it is obviously a problem with the speakers or the cabinet - it could be a mechanical resonance in some part of a speaker / cabinet, something like a loose screw or a nut, loose protection mesh on the speakers that resonates at certain frequencies, possibly a bad speaker or a speaker membrane...
Also, you might want to check the pickups on your guitar, see if the pickup core slug under the A string is much closer to the string than the other slugs so it is either picking up too much signal and distorting it or the string might be touching the slug when you play it and cause noise, also see if the string is touching something else when it vibrates...
That's the problem; you're using light gauge guitar strings. Chances are that if you are not used to playing strings that light, you're fretting hand will hit the strings with more force than is neccesary to fret them, thereby forcing them out of tune. You can solve this problem by adding more winds around the string post (three or more winds should do it), or you can switch to a heavier gauge of string.
If they're true locking tuners, they should have a notch on the back of the gear housing that you turn with a nickel to engage the locking mechanism once tuning has been established.
Also; check the intonation of the guitar itself on an electronic tuner. If it tunes right but sounds out of tune when played, this is an intonation issue, and can be solved by adjusting a small set screw that moves the individual saddle back and forth in the tune-o-matic style bridge. You can check this by tuning the string to the correct note, then playing the same string at the 12th fret and checking it against your tuner. If it rings in true, you're fine, if it comes up flat or sharp, every note on the fretboard is going to be off by that much, and you'll have to adjust accordingly (turn the screw to the right to add length and lower a sharp note, turn the screw to the left to subtract length and raise a flat note, if I remember right).
