Ok, as promised here we go for the guts of the compressor which is sold under a different brand names.
In my case it was called DiMavery.

First shot is a front/top view - second shot is from an angle.
As you can see it is a metal case and the potis have aluminium knobs.

When we open the unit we will find the track side of the pcb as can be seen in shot 3. The pcb is held in place with the DC-jack and one screw. This is enough and easy to disassemble.

By removing the screw, the pcb can be taken out as can be seen in shot 4.

As can be seen in shot 5, the potis are not pcb-mounted, which is good for the tweaker, since there can be mounted every other poti instead. Maybe the knob has to be exchanged.

Shot 6 shows the component side.

Now we come to the Footswitch:
As can be seen in shot 7 there is enough room beetween the switch-pcb and the actual pcb. Thus there can be made a new pcb with distance-bolts, carrying a miniature push-switch as they are used in DJ-mixing consoles. This is possible because - as can be seen in shot 8 - the pushbotton is activated with a strong spring, which seems to be strong enough to actvivate this little push-switches too.

Alltogether it is a very cheap possibility for the tweaker, even when he puts a total different circuit inside. The blue label can easily be removed after unscrewing the potis and replaced by an own design.

enjoy the guts below,

Hi,

The Ibanez CP10 works with a OTA BA6110. This unit has a LM3080N or CA3080 OTA like Ross or MXR Comp.

Best regards Uwe

True as this is the CA3080 and the BA6110 are, other than for the pinning, compatible in such an extend that the designs are almost the same. The Ibanez CP835,CP9, CPL, CP10 and CP5 are all clear dynacomp derived in their principle of operation. As is the Boss CS3 ...
Sorry. Plain out of planes.
