Sound great, but only with pedal

ATTENTION: the two plastic pedals of RP-70 only serve to switch between the individual effects.
But who even wants to control with your foot, when, and how strong an effect (eg wah) occurs, which must
also connect an expression pedal. In the - unfortunately only in English - operating instructions, it states:
"Any passive volume pedal can be used as in expression pedal with the RP70". I have a Boss FV-500L risen to this end, which I can use for my Yamaha keyboard. In general, however, the question arises whether it is not cheaper to buy directly an effect device with expression pedal (such as Digitech RP-255), especially the expression pedal are comparatively expensive. How stable is however an integrated effects unit in expression pedal, is another matter.

The RP-70 is not user-friendly. Every key has x-fold, so that one is always the respective setting "tickers" needs (which can be quite annoying). Without the manual as a "translator", the device is not to be used (the display 'b6' means, for example 'vibrato strength with 6 of 9'). A display that says "Vibrato" instead of an arbitrary number-letter-combination would be more helpful here.

Apart from these two points, you can create with the RP-70 with great sounds and expression pedal makes things fun (the drum machine and the integrated tuner are also very mood-lifting).

As in some reviews of an incorrect / missing power adapter is mentioned: my RP-70 was next at PSU: Harman ADS-12B-12 09012G (9V, 1.3A). The essay for German 230 volt outlets was and just needed to be plugged. In order for the device (several months) is functioning properly.
