This item is in excellent condition and was rarely used in my home studio only, which now sits idle. This item is in a child free, pet free and smoke free home. I am the original owner. I have the original owners manual. I separated all of the pages of the manual for placement into a 3-ring binder. I used a 3-hole punch on all of the pages. Other than this the manual is good. The only markings on the P330 that I see is from removal and insertion into rack spaces when repositioning the item for whatever reason. This item sounds beautiful and I hate to see it go but if I do not use it I suppose it would be better off where it can be used. The manual gives the following description: SA Sound System: Roland's SA/S sound technology. Multi Effects: Chorus, Tremolo and Equalizer. Patches: Store up to 64 different patches. Performance Controlling Functions: MIDI Control messages sent from an external device can change the performance controlling functions. Stacking Function: The stacking function allows you to set up more than one P330, increasing the number of voices to be played simultaneously. Modes: Play mode, Edit mode, Write mode and Data Transfer mode. Please, Paypal or Money order only. Shipping to USA only. Thanks.
