Opamp Adapter Mod Kits
How often have you wished you could swap out those crappy stock inline chips for a Burr Brown OPA2134PA, JRC4558D, RC4558P or one of the other popular Dual Opamp Chips? Well, now you can with this adapter and an 8 Pin Chip Socket. Simply remove the stock inline chip, pop in the adapter, socket, and your favorite opamp and experience the variety of tone that swapping opamps will give you.
Kit comes with the Adapter and a Chip Socket for swapping out Dual Opamp Chips. This is a very cool mod and I have personally had a blast swapping out chips in a variety of pedals. You will need to make sure that the chip you want to replace has enough clearance above the chip to accommodate the adapter. For pedals such as the BD-2, that have limited room for the adapter, I am selling Socket Extenders which you'll find sold below.
You will use the Socket Extender to raise the adapter and chip so the legs of the adapter may be bent over (see illustration below). This will give you room to install the Adapter Mod in a pedal like the BD-2 that has limited space. In the illustration below notice how the Socket Extender allows the Adapter Legs to be bent. This allows the Chip Adapter to be installed in pedals that have limited room. NOTE: These Socket Adapters may also be used to socket diodes, resistors, caps, etc. This makes swapping out components very convenient.

Opamp Adapter Mod Kits Installed
In the pictures above I have replaced sone of the stock inline chips of pedals with my new Adapters and Socketed Burr Brown OPA2134PA Chips. The results are unbelievably good. The OPA2134PA gives the Sustainia Tri-Gain Mod more clarity and note definition while in other pedals will render lower noise and a more focused tone. I also replaced a LM308N in my OD-308 with stacked LM308Ns.

A Word About Stacking Opamps Stacking opamps has been around for many years. Dave Barber reintroduced it to the DIY community a while back. There are some advantages. First thing I noticed was slightly more output volume. Not a lot but noticeable nonetheless. And depending on the circuit you'll get different tones from mixing and matching opamps. Sometimes two of the same type works best, sometimes not. I have chosen the combinations I feel sounded the best in the mods I offer. But, the fun is in experimentation so feel free to mix and match. Other things I noticed in my experimentation was slightly less noise and more headroom. The complexity of tone can be much improved with stacking opamps. Fullness and harmonic content seem to be enhanced also.

DIP8 to 8-Pin Single Opamp Socket Extenders
Use these Socket Extenders to install the Chip Adapter in pedals with limited space such as the BD-2. See the illustration above. The Socket Extender allows the legs of the Chip Adapter to be bent to allow it to lay closer to the PCB allowing the Chip Adapter to be installed in pedals with limited room.
NOTE: These Socket Adapters may also be used to socket diodes, resistors, caps, etc. This makes swapping out components very convenient and easy. By adding a socket where the component is on the PCB you can easily swap out different components without resoldering. Just solder a socket in each of the components holes and make experimenting simple and easy. |
By Units of Eight I mean you'll get what you see in the picture at the left. That is 8 individual sockets not 8 sets of 8.
