This is an early, heavy-duty Fender Rumble 100 model! The top handle has been removed, but otherwise, there is no damage. The sound comes out clearly. There is no crackling. This model from this era weighs around 27kg, which gives it a solid feel. The sturdy cabinet provides a unique stickiness and thickness in the low-mid range. 15-inch speaker: Equipped with a 15-inch speaker, which is larger than the current 12-inch models, it excels at producing deep bass that resonates in your core. Red LED light (Stage logo): A gimmick with a red light under the grill that lights up. (It looks very cool live! It can also be turned off) Versatile input/output: "EFFECTS LOOP (send/return)" and "XLR LINE OUT" are located on the front, allowing for smooth connection with external effects units and output to the PA system in live houses. Main functions of the front panel The roles of the knobs and switches in the photo are explained from left to right. INPUT & Select Switch: There is a switch for passive/active bass and a "SCOOP" button to cut the mid-range. EQ (Equalizer): 4-band configuration: Bass / Low Mid / High Mid / Treble, allowing for fine-tuning of the tone. CD IN: You can connect your smartphone or music player and practice along with songs (the name at the time was CD IN). LINE OUT & LEVEL: You can adjust the volume sent to the PA desk during live performances. Thank you.
