In most cases, when a new and/or updated product gets released, it will typically cause sales for a similar/related product to decline. When that happens, the only two options given to us are:
1. Raise the price of the older product
2. Discontinue it
In the end, we typically decide to discontinue it, as we want to make sure we are selling our products to customers at the lowest, most fair price possible.
An example of this is when we released our 101 Reverb Head. Once that was released, sales for the 101 Mini Head declined to the point where it only made sense to discontinue it.
