What is a bass ramp and why would you want one? | eBass
A bass ramp is a block of wood that is mounted under the strings, and is either mounted before the pickups (front-side mount,) between two pickups (mid-mount) or after the pickups (rear-side mount.) The position of the block depends on player preference. The most common bass ramp position is between two pickups, as shown above.

Designing Catch Benches and Interramp Slopes
The mining equipment used to drill and blast the rock determines the bench height. Catch benches can be left either at every mining level (single benching) or at every other mining level (double benching). Bench Face Angles. In weaker rocks, face angles are often controlled by the equipment and digging technique used while mining.

Everything You Need to Know About Cooking With Ramps
With ramps, the secret to cooking success is in simplicity. In other words, you don't need to fuss too much. Ramps can be eaten raw, like green onions or scallions, but they're frequently cooked down, like leeks. While they aren't as hardy as leeks, the leaves are much more resilient to heat than the delicate shoots of chives or scallions, so ...
