I'm designing a suite of guitar effect stomp boxes and need to decide whether I design the PCB for SMT, through-hole or a combination of both. There are a few components like POTS, switches and jacks that are better suited to through hole components since they make up the physical/mechanical build of the box. My question is should I design the PCB to be 100% through hole or would a mix of SMT and through hole components be OK considering the potential for volume manufacturing? I'd appreciate any advice. Thanks.

In medium volume (say 100-10000 pieces) mix of SMD and through-hole is fine.
In very small volume, through-hole could be cheaper as there's no need to set up stencils.
Typically you will be quoted based on the number of pads / pins, plus a fixed setup fee (which is higher for SMD, but amortises quickly in volume). The fee per through-hole pin is considerably higher than per SMD pad. In this kind of medium volume the throughhole parts will typically be soldered by hand.
I agree with you that it makes sense to stick with through-hole parts for connectors in medium-volume applications, as the SMD ones can be more hassle than they're worth. Won't be any problem for any factory / CM.
