20 Watt Guitar Amplifier Circuit Diagram

The sound is excellent and it looks amazing with this retro design and guitar amplifier style! 20+ hours of battery charge life it`s truth, not joke!

The ISOBAR6ULTRA is a sturdy well made product. It protects against surges as well as offers line noise filtering. I am a guitarist and play clubs where the a/c wiring can be an issue. I have used the ISOBAR6ULTRA in these places with great results. I use vintage tube guitar amps and feel secure with my equipment connected to the ISOBAR6ULTRA. I really like the isolated outlet setup. I can run my guitar amp on one circuit and my p/a sound system on another circuit and not have to worry about noisy ground loops. The lighted indicators on the unit give me instant status of a/c circuits feeding my equipment. I most definitely recommend this product to anyone seeking to protect their electric or electronic equipment, especially working musicians.

We used this product in the ceiling of our conference room. These speakers are VERY loud for only having a 1-watt amplifier built in. You will NEED to purchase separately, the 24 volt power supply for EACH speaker in use in order to install these and have them function. Installation is super-easy and requires NO tools if mounting in suspended ceiling tiles. I highly recommend these.

Can't beat this for the price. I have 2 of them on a 10 watt amplifier and they work flawlessly. Larger magnetic for smoother audio.

From time to time, I need the use the guitar input of my amplifier for a second microphone input - this gizmo enables me to do that withous issues.

If you’re lucky enough to have a 5-20R receptacle (which indicates it is a 20 Amp circuit, not the more common 15 Amp circuit) nearby, this thing ROCKS! When lightly loaded (100watts) it offers a runtime of 3 hours and 32 minutes. Pure sine wave output and AVR are great performance highlights, but the value of the new “SmartConnect” feature is even better. Plus, APC allows “1 Additional Year of Battery Warranty for FREE when you connect and register your Smart-UPS with SmartConnect”. An overall amazing UPS!

I needed a single power strip for all of my stereo equipment in a rack. I have a 20 amp circuit so I needed a power strip that could handle the load. This one does. The LEDs are very bright but I covered them with a dark cloth. I can still see them, but they're not a distraction. Keep in mind it requires a NEMA 20 amp receptacle with the turned blade.

It works as expected, connects easily and provides extra power. It does require a 20 amp circuit for charging, which I did not see in the requirements in the downloaded manual. It allows it to recover faster, but was unexpected.

I bought a pair of these to use with a guitar amp simulator. They sound great and allow for getting the amplifier and effects tone without having to crank up the volume to concert levels.

In 1969 I saw a solid-body electric guitar with a three-inch amplifier built into the face of the guitar. The tiny speaker was powered by a nine-volt battery inserted in the back of the instrument. Fantastic, I thought, why don't they make a suction-cup amp that sticks onto the face of the guitar? A zillion years later they did and it is fine.
