Guitar Headphone Amplifier Circuit

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.

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.

I use to as a headphone interface to a guitar tube amp DI out. It works great for that.

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.

Great mic for any kind of use. Vocals sound great as well as guitar and bass amplifier. I use this mic in my home studio and live performance.

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!

Very nice cables. I use it to connect a tube preamp to guitar amplifier and they work great. Love the color!!!

I bought the Rolls Headphone Amplifier to allow several people to simultaneously monitor an audio feed and it has worked well. A power-cube is included for use when a power outlet is available, however I am using it in the Field so the 9v battery which can power it allows me to use the Rolls Amplifier anywhere. I am pleased with the rugged metal construction and the simple power switch and individual level controls, the Rolls sounds wonderful and I have tested it with several different portable Recorders and Headphones and I am quite pleased and would certainly purchase it again and can recommend it wholeheartedly.

This is probably the best solution for a portable, pro headphone amplifier at the $ price point. What sold me about this unit was its wide range of input configurations and the fact that it does have both size headphone output jacks, which is perfect for working with clients who have their own headphones but not the adapter. These amps have plenty of clean, quiet gain. More than you will need and enough to blow up cans. It doesn't have an input trim so you ought to have some gain control at your source output. Your best bet is to run signal into this thing at unity gain. It is built very well and has a solid, steel chassis. Built in the USA, too.All in all a great piece of equipment that will save the day for only $
