€ 30 bought, sold € 32 I used it 2 times, at a reception in a receiver, the second during a weekend with family ... with headphones, since I moved successively pod2 and Tonelab.
I appreciated for its small size and the ability to operate on batteries ... its portability.
The option of "mid cancel" supposed to remove the central band is a piece innéficiente, either with or with mp3 wave.
The sounds produced are poor, without relief, it produces the same breath as many pre-amp, the fault of a faulty preamp, one must push the master volume and play with the drive to raise the level without getting a total mush.
I issue a reservation anyway because to overcome all these problems I did go into a Boss BD-2, and here with this "big foot", we go back the noise, heat and drive sound but at the expense of portability.
Reasonable value at 20-30 €.
Given the quality of its basic quality and low options, I will not repeat that choice.
I put 3 because it is convenient for budget or beginners hesitant to practice with headphones.
