As advertised, great value for money even if there are no instructions

Bargain purchase. Assembled, high-quality workmanship and even with pins! There are no instructions (not even which grip is which), but this is for some reason typical of most Chinese products, given the effort involved in designing and manufacturing these type blocks. Don't buy if you need instructions! Actually, you shouldn't buy such Chinese blocks if you need instructions.

Pros
  • . It includes a 10-way toneboard preamp, as well as treble, alto, bass and volume controls.
Cons
  • Discontinued model

<Nine dollars! Install a flat equalizer, get a flat response! Brilliant!

Buy this preamp. Bring your soldering iron to it, remove the two regulators (7815 and 7915) and put in a new power supply. Powered by a pair of 9V batteries! Gain Load: +20dB flat EQ. The equalizer section can be used. Not bad. Boosts (+8dB) and cuts (-15dB) the bass below 200Hz. The midrange (+/-8dB) should be around 700Hz, but it affects the high frequencies a lot. The Treble control boosts (+8dB) everything above 2kHz or can cut (-15dB). Sounds good when the equalizer is set to a flat level.

Pros
  • We really value every customer's opinion in order to improve the sale and if you are not satisfied with anything please contact us for the best possible solution.
Cons
  • Quick Start Guide
