18watt Build Checklist (Tremolo or TMB)

New! A check list for the parts you need for your 18watt build.

The list is roughly in the order you will need the parts.
The required quantities are shown next to the default items.
There are options available for some parts. Read each section carefully, adjust the quantities if needed; and add the items to your cart.
