J'ai encore la mienne et je ne me souviens pas qu'il y a une prise USB, celà dit, oui la marque est morte depuis longtemps.
“The type of cap is not as important as the value of the cap, for guitar. In an Amp, your cap type is much more important, as the signal is being passed through the cap all the time. In a guitar, you’re not hearing the cap itself, you’re hearing what the cap is impeding”. Lindy Fralin
