"The Tube Mkes a Huge Difference"
If you doubt that the tube in this makes any difference, try swapping the cheap, noisy Chinese tube in this with a Tung Sol of an Electro-harmonix 12AX7, and you will hear a monstrous difference. I use the versions with the meter on it, and I installed latched Tung Sol tubes in two of them, and what a huge difference. Sweet tone, low noise, and low microphonics. These preamps are great with great tubes in them. I own 4 of them, and I have tried several tubes in each, and they all made a huge difference in the performance of each of the pre amps. So, I highly recommend these pre amps, because they are a great price, very sturdy and can take a beating, and they sound great with a good tube. So, my suggestion is to keep at least one of these under $50 pre amps on hand, and make sure that you change the tube. I know from my own experience and my own use that if you change the tube in this to a higher quality, lower microphonic tube, you will have a great little pre amp.

Sound
Sound quality relies heavily on the type of tube in it. Highly recommend Tung Sol or EH tubes

Features
The one with the Meter on it is more useful, but this one is fine. I use the MP to add a tad bit more gain in the front of my chain on one of my amps. I took away one star on this model because this one doesn't have the meter on it.

Ease of Use
just turn the dials up or down read more

Quality
never had any issues with it. I have 4 and they are all working great

Value
Less than $50? Worth it

Manufacturer Support
if you have questions, they take care of you

The Wow Factor
To be honest, I have been recording with these preamps as the pre amps for my condenser mics, and I really like them. I am actually blown away at how good they sound with the replacement tubes.

Musical Background:
16 year vet, Bluntface recording artist, guitarist

Musical Style:
Experimental death metal
