If any damage is found, notify the shipping company and call CARVIN immediately. SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to reship your amp, always use the original carton and packing material. [. . . ] Now, go to the "Graphic EQ" and make the final adjustment's to your "Lead" tone. Be sure the Graphic is switched to the Lead position. Again, the Graphic EQ is an active circuit so a little adjustment goes a long way. The thing to remember when using your X-Amp is that it is highly responsive and many of the tendencies to extreme settings acquired by using "passive" type tone circuits will need to be re-learned to get the ultimate benefit from your X-Amp. The sounds are all there and the possibilities are endless--have fun. EXAMPLES OF X-AMP CONTROL SETTINGS In order to get your "sound" from the X-amp you will probably need to spend a bit of time trying various combinations of amp settings and guitar settings. We have put together the following "recipes" for various sounds which we hope will get you started. In order to get the sounds described below set the controls as described and then set your RHYTHM or MASTER volume control for the volume you want. Set your guitar volume at maximum and tone for full treble. Use your "lead" pickup for the "Marshall" type distortion and your "rhythm" pickup for "Boogie" type distortion.

These are shorting type jacks with input resistor arrangement (R62 & R63) such that the LO input is attenuated 6 dB with respect to the HI input when either jack is used alone. If both jacks are used simultaneously then they each will have the same sensitivity. The signal selected at A5(A) feeds the effects loop drive amp A4(B). If an outboard effects is patched into the loop then A4(B) drives the effects input and the effects output returns to A5(B) via Q10. If no effects is patched in then the send signal feeds the return by way of R160. FET switches Q9 and Q10 toggle in response to the EFF 1 button on the FS36 footswitch. The send and return levels are varied simultaneously by the effects level switch. The signal returned from the effects loop is processed through two tone control stages at A1(A and B) and then fed to both the reverb drive amp IC3 (A and B) and the reverb return summing amp A2(A). When the front panel tone controls are set to "5" these stages have a flat frequency response and unit gain. The reverb unit is driven by the two op amps of A3 operated in paralleled for increased current capability. Reverb drive equalization is provided by R58 and C31. [. . . ] Allow approximately 10 days for servicing. Include a check for $15 to cover the return shipping charges or we can ship the items back COD for $15 (the cost of shipping) plus the current COD fee. Speaker Systems: If you require a loudspeaker repair, you should remove the defective component (speaker) to save on shipping charges. To avoid damage, ship only in the original carton (save your cartons--a replacement is $5 plus $5 shipping) · REPAIRS OUT OF WARRANTY 1 . [. . . ]
