FREQUENTLY ASKED QUESTIONS 
 

How do I hook up this thing? 
 

-

 

See Section 2, beginning on page 3. 

 
 

Is the FX loop series or parallel?  Active or parallel? 

 

-

 

The FX loop is series, and is currently parallel.  However, we have plans to release an option for a tonally 
transparent solid-state FX loop.  Stay tuned! 

 
 
When I plug effects into the effects loop, my tone noticeably changes.  Sometimes the effects don’t sound quite right. What’s 
the deal? 
 

-

 

Generally, what you’re hearing is a significant mismatching of impedances, and/or an overloading of the effect 
unit itself. Most rack-mount units have different input impedance than pedals, and thus can 

sometimes 

function fine without a buffer before them. In addition, 

some 

of these rack-mounted effects can pad the 

volume they receive, preventing it from overloading. Pedals do not have proper input impedance or padding 
ability, and therefore do not play nicely.  
 

-

 

For best results, an effects loop interface like the C-lator or Klein-ulator should be used with the Son of Yeti 
amplifiers.  These units prevent impedance mismatching, as well as provide the ability to pad down the 

volume sent to the effects units hence preventing any overloading.
