The official Positive Grid Spark Amp User Manual (v0.6) can be downloaded below (see Article Attachments)
However, an ‘unofficial’ manual is also being maintained by some Spark Amp users in the Spark Amp User Manual Authors Group on Facebook.
They’ve done a wonderful job and you will find much more information in this (unofficial) document than in the default user manual.
